What does preventive dentistry cover?

Preventive dentistry aims to lower the risk of dental disease, such as tooth decay and gum disease. This page covers tooth decay (dental caries) and NHS guidance on dry mouth, varnish, sealants and mouth ulcers. The government's Delivering Better Oral Health toolkit calls tooth decay largely preventable and advises brushing with fluoride toothpaste and keeping sugary food and drink to mealtimes. For ongoing care, see routine dental care at our practice or a guide to routine dental care.

How does tooth decay start?

Tooth decay starts when bacteria turn sugars into acids that demineralise enamel, Delivering Better Oral Health explains. Early decay may cause no symptoms and can be reversed. Untreated, it can reach the pulp, shown in how a tooth is built. Read how cavities form.

How does fluoride help prevent tooth decay?

Fluoride helps prevent tooth decay by encouraging the tooth surface to remineralise, Delivering Better Oral Health says. Where needed, our dentists prescribe high-fluoride toothpaste. See how fluoride protects teeth.

Why does diet matter for tooth decay?

Diet matters for tooth decay because how often you have sugar counts as well as how much, Delivering Better Oral Health says. Frequent sugar leaves too little time for enamel to remineralise between acid attacks. Read how sugar and snacking affect teeth.

Where does gum disease prevention belong?

Gum disease prevention belongs in the dental hygiene section, because gum disease is a different condition from tooth decay. NHS guidance describes it as red, sore gums that bleed, caused by a build-up of plaque. For daily gum care, browse this section of our hygiene guides.

Frequently asked questions

How often should I have a dental check-up?

It depends on your oral health. NHS guidance says your dentist sets the gap between check-ups, which could be as short as 3 months or as long as 2 years, or up to 1 year if you are under 18. The practice's standard recall interval for a healthy adult is 6 months.

What are fluoride varnish and fissure sealants?

Both are preventive treatments the NHS describes. Fluoride varnish is painted onto teeth; the NHS says children should be offered it at least twice a year from age 3. A dentist can also prescribe it to reverse early decay. Fissure sealants, a thin plastic coating on back teeth's chewing surfaces, can be applied once adult back teeth start coming through.

When should a mouth ulcer be checked?

NHS guidance says to see a GP about a mouth ulcer lasting over 3 weeks. It sets no time limit for a red or white patch or lump in your mouth or on your lip: see a GP. These may signal mouth cancer; dentists can also help. Where oral cancer is suspected, the practice makes the urgent two-week referral itself.

Does a dry mouth increase the risk of tooth decay?

Yes. NHS guidance says you are more likely to get tooth decay if you have a dry mouth. Delivering Better Oral Health notes that certain medicines may reduce saliva flow, which raises the risk. If your medicine leaflet lists dry mouth, mention it at your check-up.

How quickly can a new patient be seen?

A new patient's first appointment is usually available within a few days. The new patient appointment takes 30 minutes. You can complete your medical history online before the visit, and you should bring a list of your medicines. There is free parking directly outside.
