Meet Marisa, your London Dental Hygienist.

A GDC-Registered Dental Hygienist & Therapist treating patients from Perivale, Greenford, Ealing, Alperton and other surrounding areas in London

I’m Marisa Lennie, a GDC-registered Dental Hygienist & Therapist based in Perivale, London. I help patients with a wide range of dental treatments, from a routine hygiene clean and gum disease treatment to fillings and fluoride treatment, for adults and children.

I believe good dental care goes beyond treating problems when they arise. It is about understanding the factors that affect oral health and using appropriate preventive care to reduce the risk of future disease. Alongside my clinical work, I remain actively involved in the wider dental profession through education, training and professional development.

My Approach

Prevention-led,
evidence-based

Guided by NICE and DBOH, explained in plain language.

I chose dental hygiene and therapy after seeing adults and children struggle with problems they didn’t understand or know how to prevent. That is why education and prevention come first in my care, guided by current evidence.

I have treated hundreds of adults, children and nervous patients, and every mouth is different, so every plan is personal. For nervous patients, I allow longer appointments, agree signals and never rush. The most rewarding part is seeing patients return with healthier gums.

What I do

Hygiene and therapy services

How I can look after your teeth

  • Smiling woman with a bright, natural smile

    Dental Hygiene

    In a hygiene clean, I remove plaque and tartar with ultrasonic and hand tools, check your gums for early signs of disease, and give advice based on your own risk factors, such as smoking or diabetes.

  • Dental professional pointing to a tooth on a model of the teeth

    Dental Therapy

    Within my scope as a dental therapist, I treat decay with fillings and apply fluoride varnish to strengthen enamel and help with sensitivity. Treatment outside my scope, such as root canal, is referred to a dentist.

  • Young girl in the dental chair practising brushing with a toothbrush

    For Children

    I make visits easy for children with a gentle, explain-as-I-go approach, protect new teeth with fissure sealants and fluoride varnish, and keep an eye on how their teeth are coming through.

  • Dental professional using a model of the teeth to explain a treatment to a patient

    For Nervous Patients

    I take extra time to explain each step, offer regular breaks, and use a calm, gentle approach so anxious patients feel safe, listened to and in control throughout their visit.

Why choose me

Why London patients choose me for their hygiene treatments

I have worked with patients since 2014, first as a dental nurse and, since 2019, as a GDC-registered Dental Hygienist & Therapist. Those years in the surgery have shown me how much a calm, unhurried appointment matters, especially if you feel nervous about dental treatment. My patients can expect gentle, personalised care, clear explanations and advice based on current evidence. My focus is on prevention, gum health and helping every patient feel comfortable and confident looking after their teeth and gums.

Treatment detail

Book now: Hygiene Clean

Hygiene Clean

A routine hygiene visit that removes plaque, tartar and surface staining from above the gumline, then polishes the teeth so they feel smooth and stay easier to clean at home. More about a hygiene clean

Best for
Adults and teenagers with generally healthy gums who want to keep them that way, and anyone whose brushing leaves tartar behind between visits.
Suggested frequency
Every 6 months for most people; every 3–4 months if you smoke, have crowded teeth or your gums bleed when you brush.
Appointment length
45 minutes

What's included

  • Gum health check with bleeding and pocket-depth screening
  • Ultrasonic and hand scaling above the gumline
  • Polish to lift light staining and smooth the tooth surface
  • Tailored brushing, flossing and interdental brush coaching

Good to know

Anaesthetic is not usually needed, though numbing gel is available if you are sensitive. Gums can feel tender for a day and teeth briefly sensitive to cold; you can eat and drink straight away.

Hygiene Clean (Extended)

The same hygiene treatment with a full hour of clinical time, so heavier tartar, stubborn staining and harder-to-reach areas are all dealt with thoroughly in one visit. Compare the standard and extended visit

Best for
Anyone who has not seen a hygienist for a year or more, or who has visible tartar, tea, coffee or tobacco staining, crowded teeth, braces, bridges or implants.
Suggested frequency
Every 6 months, or every 3–4 months if build-up returns quickly. Many patients step down to the 30-minute visit once things are stable.
Appointment length
60 minutes

What's included

  • Full gum health check with bleeding and pocket-depth screening
  • Thorough ultrasonic and hand scaling, upper and lower arches
  • Stain removal and polish, including around brackets and implant margins
  • Extended time for personalised cleaning-technique coaching

Good to know

Gums may feel tender for a day or two after a longer clean. Avoid strongly coloured food, drink and tobacco for 24 hours so new staining does not settle straight back in.

Deep Clean (Root Surface Debridement)

A targeted, quadrant-by-quadrant clean beneath the gumline that removes hardened deposits and bacteria from the root surfaces, so inflamed gum tissue can heal and reattach. More about deep cleaning

Best for
Diagnosed gum disease (periodontitis) with deeper pockets, persistent bleeding, bad breath or recession identified at your assessment.
Suggested frequency
A course of 2–4 appointments, then a review at 8–12 weeks to measure how the gums have responded.
Appointment length
60 minutes per quadrant

What's included

  • Full periodontal charting with pocket depths recorded per tooth
  • Local anaesthetic so treatment stays comfortable throughout
  • Ultrasonic and hand debridement below the gumline
  • Risk-factor review (smoking, diabetes, medication) and a written plan

Good to know

Expect tenderness and sensitivity for a few days, and gums that look slightly shrunken as swelling settles, which is a sign of healing. Lukewarm salt-water rinses help; day-to-day plaque control at home is what decides the final result.

Periodontal Maintenance

The ongoing supportive appointment that keeps treated gum disease stable: pockets are re-measured, returning deposits removed, and your home routine adjusted wherever readings have slipped. More about periodontal maintenance

Best for
Patients who have completed deep cleaning, and anyone with a history of gum disease, dental implants or early tooth loss in the family.
Suggested frequency
Every 3 months at first, extending to every 4–6 months once your readings stay stable.
Appointment length
45 minutes

What's included

  • Re-charting of pocket depths, bleeding scores and recession
  • Debridement of any sites that have relapsed
  • Implant and crown margin check where relevant
  • Your progress compared against previous readings, in writing

Good to know

Mild sensitivity for a day or two is normal. Missed maintenance visits are the most common reason gum disease returns, so keep to the interval your clinician sets for you.

Children's Hygiene & Fluoride Varnish

A short, prevention-focused visit that builds confidence: teeth are cleaned, decay risk is assessed with the parent present, and high-fluoride varnish is painted on to strengthen enamel. More about children’s visits

Best for
Children and teenagers from around age 3, especially those in braces, with early white-spot marks or a history of fillings.
Suggested frequency
Twice a year; fluoride varnish can be applied up to four times a year for higher-risk children.
Appointment length
45 minutes

What's included

  • Gentle clean and age-appropriate brushing demonstration
  • Decay and diet risk assessment with the parent present
  • Fluoride varnish application (22,600 ppm), no injections needed
  • Fissure sealant advice for newly erupted adult molars

Good to know

No eating or drinking for 30 minutes afterwards, and no brushing until the next morning, so the fluoride stays in contact with the enamel and does its job.

General Hygiene Check-Up

A full oral health review carried out directly by a dental hygienist or therapist under GDC direct access, without needing to see a dentist first. Covers a clinical examination, gum health assessment and an oral cancer screening. What happens at your first visit

Best for
Anyone due a routine review, new patients wanting a full assessment, or those who would rather see a hygienist directly than book with a dentist first.
Suggested frequency
Every 6–12 months, or more often if your risk factors mean you need closer monitoring.
Appointment length
45 minutes

What's included

  • Updated medical history and a discussion of any changes since your last visit
  • Clinical examination of your teeth, gums and soft tissues
  • Oral cancer screening, checking the mouth, tongue, lips and neck for anything unusual
  • Gum health assessment with pocket-depth charting and bleeding checks
  • A written summary of findings, with referral to a dentist if further treatment is needed

Good to know

Dental hygienists and therapists can see patients directly without needing a dentist referral first. If a cavity or other issue needing restorative treatment, such as a filling, is found, you'll be referred on to a dentist.

Dental Hygiene Care

Preventive care for healthier gums

As a dental hygienist, I help patients improve and maintain their oral health through personalised preventive care. During each appointment, I assess the health of your teeth and gums by looking for signs of plaque, tartar, bleeding and early gum disease before carefully removing harmful deposits that are difficult to clean effectively at home.

In my experience, patients who see the biggest improvement are rarely the ones who brush hardest. They’re the ones who learn which two or three areas their own routine keeps missing. Many are surprised to find those spots are the same every day. Using what I see in your mouth on the day, I give practical advice for your mouth, whether you have crowded teeth, restorations, implants or a history of gum problems.

My aim is not simply to provide a thorough professional clean, but to help you understand why problems develop, make small changes that are realistic to maintain, and feel confident keeping your teeth and gums healthy between appointments.

  • Plaque & Tartar

    Removed from tooth surfaces and around the gumline.

From the chair

What this looks like in practice: What to expect at your appointment

“Most people arrive with a question or a worry: gums that bleed when they brush, staining, sensitivity, or simply that it’s been a while since their last visit. Whatever brings you in, this is how I run a typical appointment.”

Marisa LennieDental Hygienist & Therapist · GDC 252605

  1. Consultation

    Before I pick up an instrument, we talk: your medical history, any medicines, smoking, and anything that’s worrying you or that you’d like me to focus on.

  2. Assessment

    I check your teeth and gums around every tooth, noting tartar, staining and any areas that bleed, so we have a clear starting point to compare against at your next visit.

  3. Treatment plan

    I show you what I’m seeing and explain your options, how long it will take, and whether more than one visit makes sense. If you’re nervous, we agree a signal so you can ask me to pause at any time.

  4. Treatment

    I work section by section with ultrasonic and hand instruments, checking in with you as I go. If an area is tender, we talk about ways to keep you comfortable before I continue.

  5. Aftercare

    I keep the last few minutes for practical advice you can use at home, such as finding the right interdental brush sizes in front of a mirror, and we agree when I should see you next.

Everyone’s mouth is different. Your own plan is based on your assessment on the day, and this is general information, not personal clinical advice.

Patient reviews

What patients say.

  • Smiling family with a young child
  • “Great practice with an attentive and friendly team. I’ve been to several hygienists/therapists before and found Marisa to be by far the most gentle but thorough. Her assistant was also super friendly. I’ll be happy to have my treatment here again in the future and can genuinely recommend the practice to anyone.”

Frequently asked questions

What does a dental hygienist do?

A dental hygienist's main focus is preventing and treating gum disease and helping you keep your natural teeth for life. That means removing plaque and tartar through scaling and polishing, checking for early signs of gum disease and decay, applying fluoride varnish or fissure sealants where needed, and giving practical advice on brushing, flossing and diet that actually fits your routine. As a dental hygienist, I see each visit as preventive care rather than just a clean - I am looking for small changes early, before they turn into bigger problems, and helping patients build habits that genuinely stick.

Link to this answer

How often should I visit my dental hygienist?

NICE guidance recommends that recall intervals are based on your individual risk of dental and gum disease rather than a fixed rule for everyone, ranging from a few months up to a maximum of 24 months for adults at low risk (12 months for under-18s). In my own practice, most patients do best with a hygiene visit every three to six months, especially if you have a history of gum disease, smoke, have diabetes, or notice plaque building up quickly. At your first appointment I will assess your gum health and risk factors and agree a recall interval with you, then review it at every visit.

Link to this answer

Does a dental cleaning hurt?

For most patients, a routine hygiene appointment is comfortable rather than painful - you may feel some pressure, and occasional sensitivity around the gum line if it has been a while since your last visit or your gums are inflamed. If you already have gum disease, the first visit or two can feel a little more sensitive while the inflammation settles, but this usually improves quickly. I always explain each step as I go, work gently, and can offer numbing gel or regular breaks if you are anxious or have sensitive teeth, so please tell me if anything feels uncomfortable and I will adjust.

Link to this answer

How can I tell if I have gum disease?

The earliest sign of gum disease, gingivitis, is usually bleeding gums when you brush or floss, along with redness and swelling. Left untreated, this can progress to periodontitis, where you might also notice gums pulling away from your teeth, persistent bad breath, sensitive teeth, or teeth that feel slightly loose. Gum disease is often painless in its early stages, which is exactly why regular hygiene visits matter - I can spot the warning signs, measure your gum health with a simple probe, and start treatment before any damage becomes permanent.

Link to this answer

What is the difference between a dental hygienist and a dental therapist?

Both dental hygienists and dental therapists are GDC-registered professionals who focus on prevention - cleaning, gum health and patient education - but a dental therapist's training also covers certain restorative treatments, such as fillings and extractions in children. I am qualified and registered as both a dental hygienist and a dental therapist, so I can combine thorough preventive hygiene care with a broader range of treatment where appropriate, all within the same appointment.

Link to this answer

Can I book an appointment with a dental hygienist in London without seeing a dentist first?

Yes. Since 2013 the General Dental Council has allowed patients to book with a dental hygienist or dental therapist directly, without a prescription or referral from a dentist. This is called direct access. You can book with me at Bilton Road Dental Practice in Perivale for a check-up, a hygiene clean, gum treatment or prevention advice as your first appointment. If I find something that needs a dentist, such as a cavity that needs restorative treatment, I’ll explain what I’ve seen and refer you on.

Link to this answer

I’m a new patient, can I book with the hygienist in your practice in London?

Yes, I see new patients at Bilton Road Dental Practice, 56 Bilton Road, Perivale, UB6 7DH. The best first appointment is a General Hygiene Check-Up: 45 minutes and £95, covering a full review of your teeth, gums and mouth, a gum health check and an oral cancer screening, with a written summary of what I find. To book, call the practice on 020 8997 0933 or send an enquiry through this website, and we’ll arrange a time that suits you.

How much does a private dental hygiene appointment cost in Perivale/Ealing?

Appointments with me at Bilton Road Dental Practice in Perivale start at £95. A General Hygiene Check-Up, a Hygiene Clean, Periodontal Maintenance and a Children’s Hygiene & Fluoride Varnish visit are each £95 for 45 minutes. An Extended Hygiene Clean is £110 for 60 minutes, and a Deep Clean (Root Surface Debridement) for diagnosed gum disease is £130 per quarter of the mouth. Before any treatment starts, you get a written plan with the proposed treatment and a realistic indication of its cost.

Link to this answer

How should I prepare for my dental hygiene or therapy appointment?

Your first visit starts with a conversation about your health, so it helps to bring a list of the medicines you take and their doses (a photo of the boxes is fine), any recent letters about your health that might be relevant, details of any previous gum treatment, and your questions written down. Tell me about any allergies, for example to latex or local anaesthetic, and whether you’re pregnant. If you’re nervous, mention it when you book or at the start of the visit: nothing is done without me explaining it first, and you can ask me to pause at any time.
