Dental decay is the most common reason people seek dental treatment, yet it remains one of the most preventable conditions in oral health. At Conway House Dental Practice, we take a proactive approach: identifying decay as early as possible, treating it conservatively, and — where it has progressed — drawing on our in-house team of specialists to restore your tooth and protect your long-term oral health.
We welcome patients from Marlow, Beaconsfield and High Wycombe who are looking for clear, honest advice and a dental team equipped to manage everything from a straightforward filling through to complex restorative and specialist care — all under one roof, without the need for external referrals.
Dental decay — also known as tooth decay or dental caries — occurs when bacteria in the mouth produce acids that gradually erode the hard outer layer of a tooth (the enamel). These bacteria feed on sugars from food and drink, releasing acids that weaken and dissolve enamel over time.
If left untreated, decay progresses inward through the enamel into the softer dentine beneath, and eventually into the pulp — the innermost part of the tooth containing the nerve and blood supply. At this stage the tooth can become acutely painful and infected, requiring more complex treatment to save it, or extraction if it cannot be preserved.
Decay can affect anyone at any age. Children, teenagers and adults all face risk — though the causes, patterns and treatment approaches differ, which is why our clinical team includes specialists in paediatric dentistry, endodontics and restorative dentistry alongside our general dental team.
Whether you have a specific concern, have not been seen for some time, or are simply looking for a dental team you can trust in Marlow, Beaconsfield or High Wycombe, we are here to help.

Decay results from a combination of factors that create the right conditions for acid damage:
Secondary decay — older fillings or crowns with worn margins can allow bacteria to re-enter the tooth underneath.

The most effective treatment for dental decay is preventing it from occurring in the first place. Our team will always provide personalised preventive advice as part of your care, but the fundamentals are:
If you have not been seen for some time, or if you have a specific concern, a comprehensive dental health assessment is the right place to start. We will check thoroughly for decay, assess your gum health, and give you an honest picture of what, if anything, needs attention.

For children, dentists often apply fluoride varnish during check-ups to help prevent tooth decay and keep their smiles healthy. Regular dental visits and a balanced diet also play a key role in keeping your teeth strong and cavity-free

One of the challenges of dental decay is that it is often painless in its early stages. By the time discomfort begins, the decay may already be well established — another reason why regular check-ups are so valuable. As decay develops, you may notice:
If you are experiencing any of these symptoms, contact us promptly. The earlier decay is identified and treated, the simpler and less costly treatment will be.
Treatment depends on how far decay has progressed. Our priority at every stage is to preserve as much healthy tooth structure as possible.
Early Decay: Fluoride and Preventive Care
In its very earliest stage — before a cavity has formed — decay can sometimes be arrested and even reversed using professionally applied fluoride. Fluoride varnish remineralises weakened enamel and can halt early lesions before they require operative treatment. We also provide detailed, personalised advice on diet and oral hygiene to reduce your individual risk going forward.
Mild to Moderate Decay: White Composite Fillings
Once a cavity has formed, the decayed tissue must be removed and the space restored. At Conway House, we use tooth-coloured composite resin fillings that blend seamlessly with your natural tooth. These are durable, mercury-free and aesthetically superior to older amalgam fillings. For patients wishing to replace existing silver restorations as part of an overall plan, we can discuss this at your consultation.
Significant Decay: Inlays, Onlays and Crowns
When decay has destroyed a large portion of tooth structure, a simple filling may not provide sufficient strength. A porcelain inlay or onlay — precision-fitted to the remaining tooth — offers a more durable and aesthetic restoration. Where the tooth has been significantly weakened, a crown may be recommended to protect and reinforce it. Our Consultant and Specialist in Restorative Dentistry, Mr Ashok Vijayakumar, leads more complex cases, bringing a level of skill and judgement that ensures lasting results.
Advanced Decay with Pulp Involvement: Endodontic (Root Canal) Treatment
When decay has penetrated deep enough to infect the dental pulp, endodontic treatment becomes necessary to save the tooth. The infected tissue is carefully removed, the root canals cleaned, shaped and sealed, and the tooth restored with a filling or crown. At Conway House, complex root canal cases are treated by our clinician with a practice limited to endodontics, using advanced techniques to maximise comfort and long-term success. Saving a tooth through root canal treatment is almost always preferable to extraction — it preserves your natural bite, prevents bone loss and avoids the cost and complexity of a replacement prosthesis.
Decay Beyond Saving: Specialist Oral Surgery
Where a tooth is too severely decayed to be restored by any means, extraction becomes necessary. Surgical extractions — including broken-down, infected or otherwise complex teeth — are performed at Conway House by our Consultant Oral Surgeon, Mr Dipesh Patel. Following extraction, our team can advise on tooth replacement options, from bridges and dentures through to dental implants, ensuring the loss of one tooth does not lead to further deterioration of your bite or jawbone.
Not all cases of dental decay are straightforward. Our in-house team of GDC-registered specialists means that where your care requires expertise beyond routine dentistry, that expertise is available immediately — without referral, delay, or the inconvenience of attending another practice.
Endodontics — Saving Teeth with Deep Decay
Root canal treatment carried out by a specialist endodontist delivers significantly higher success rates than the same procedure performed by a general dentist, particularly for teeth with complex anatomy or where previous treatment has failed. If your tooth has been painful, has a recurring abscess, or has already had a root canal that has not resolved, our endodontic specialist can assess whether the tooth can be saved and plan the most appropriate treatment.
Periodontics — Decay at and Below the Gumline
Root surface decay is an increasingly common presentation, particularly in patients with gum recession or a history of periodontal disease. When decay develops in areas exposed by receded gums, the underlying gum condition must be managed alongside the tooth itself. Our Specialist in Periodontics, Dr Mital Patel, treats the gum disease driving recession and works alongside our restorative team to create the stable foundation needed for a lasting restoration.
Restorative Dentistry — Rebuilding Heavily Damaged Teeth
Where decay has been extensive — affecting multiple surfaces, underlying a crown, or requiring significant rebuilding of tooth structure — the involvement of our Specialist in Restorative Dentistry ensures the result is planned and executed to the highest standard. This is particularly important for patients whose decay has caused the failure of existing restorations, or who need a coordinated plan to stabilise and restore several teeth at once.
Paediatric Dentistry — Protecting Children from the Outset
Tooth decay in children is both common and largely preventable. Our Specialist in Paediatric Dentistry provides a child-centred environment where treatment is managed gently and positively — building the habits, confidence and trust that underpin a lifetime of good oral health. Decay in baby teeth matters: it can cause pain and infection, affect developing permanent teeth, and — if managed badly — leave a child with long-lasting dental anxiety. Early specialist intervention changes that trajectory.
Early decay often causes no symptoms at all, which is why regular check-ups are so important. As it progresses, you may notice sensitivity to sweet, hot or cold foods, visible dark spots or holes in a tooth, or toothache. If you experience any of these, contact us promptly — the sooner decay is treated, the simpler and more affordable the treatment.
In its very earliest stage — before a physical cavity has formed — decay can sometimes be halted or reversed with professional fluoride treatment and improved hygiene. Once a cavity is present, however, the damaged structure cannot regenerate; the decayed tissue must be removed and the tooth restored.
Not necessarily. Pain can have several causes, including sensitivity, a cracked tooth, or early pulp irritation that does not yet require root canal treatment. A clinical examination and X-rays will determine the extent of the decay and the appropriate treatment. We will always explain your options clearly before proceeding with anything.
Yes — significantly. Decay in baby teeth causes pain and infection, can damage the developing permanent teeth underneath, and affects spacing. Our Specialist in Paediatric Dentistry treats children’s decay gently and positively, addressing the problem while building a constructive relationship with dental care that serves them well for life.
This depends on the extent of decay and the treatment required. A straightforward composite filling is one of the most affordable treatments in dentistry; complex restorations or specialist involvement are priced accordingly. We provide clear, itemised costs before treatment begins, with no surprises. Flexible payment options are available, including 0% finance subject to status.
