Preventative Dentistry: How to Maintain a Healthy Smile for Life

Preventative dentistry is about caring for your teeth and gums before problems become painful or require more extensive treatment. It combines effective daily cleaning with professional examinations, personalised advice and treatment where appropriate.

Preventing every dental problem is not always possible. Teeth can still become damaged, medical circumstances can change and some people are naturally at greater risk of decay or gum disease. However, a consistent routine can significantly reduce avoidable risks and make developing problems easier to identify.

The most effective approach is usually a simple one: brush thoroughly, clean between your teeth, limit frequent sugar, attend dental appointments when recommended and ask for advice when something changes.

What Does Preventative Dentistry Include?

Preventative dentistry covers the steps taken at home and within a dental practice to protect your oral health.

This may include:

• Routine dental examinations
• Personalised brushing and interdental cleaning advice
• Assessment of your teeth, gums and soft tissues
• Professional plaque and tartar removal where needed
• Dietary and fluoride advice
• Fluoride varnish or fissure sealants when clinically suitable
• Monitoring existing fillings, crowns and other dental work
• Support with smoking, dry mouth or teeth grinding
• Protection against dental injuries

The advice you receive should reflect your own dental history and level of risk. You can learn more about the practice’s approach on its preventative dentistry page.

Brush Twice a Day With Fluoride Toothpaste

Brushing removes plaque from the accessible surfaces of your teeth and around the gum line. Plaque is a sticky film containing bacteria that can contribute to tooth decay and gum inflammation when it is not controlled.

Brush for around two minutes twice a day, including last thing at night and on one other occasion. Try to clean the outer, inner and biting surfaces of every tooth rather than concentrating only on the areas you can see when smiling.

For most adults, toothpaste containing between 1,350 and 1,500 parts per million of fluoride is suitable unless a dental professional recommends otherwise. The fluoride concentration is normally shown on the packaging as “ppm”.

After brushing, spit out the excess toothpaste but avoid immediately rinsing with water. Rinsing washes away the concentrated fluoride left on the teeth.

Choose a Toothbrush You Can Use Effectively

Both manual and electric toothbrushes can clean teeth effectively when used correctly. The most suitable choice is one that feels comfortable, reaches the back teeth and allows you to clean every surface consistently.

A small brush head with soft or medium bristles is appropriate for many people. Hard bristles and aggressive scrubbing are not needed to remove plaque and may irritate the gums or contribute to wear around the gum line.

Replace a manual toothbrush or electric brush head when the bristles become bent, flattened or frayed. This is usually around every three months, although some brushes wear out sooner.

If your toothbrush becomes splayed within a few weeks, you may be applying more pressure than necessary. A dentist or hygienist can demonstrate a gentler technique.

Clean Between Your Teeth Every Day

A standard toothbrush cannot always reach the narrow spaces between teeth. Plaque left in these areas can contribute to gum inflammation and decay between neighbouring teeth.

Depending on the size of the spaces, suitable options may include:

• Dental floss
• Interdental brushes
• Single-tufted brushes
• Other cleaning aids recommended by your dental team

Interdental brushes are available in different sizes, and you may need more than one size around your mouth. The brush should fit closely without being forced between the teeth.

Some bleeding may occur when you first begin cleaning an inflamed area. Do not use this as a reason to stop, but arrange dental advice if bleeding persists or becomes worse.

Use Mouthwash at the Right Time

Mouthwash is not a substitute for brushing or cleaning between your teeth. It should only be used as an additional product when appropriate.

Avoid using mouthwash immediately after brushing because it can wash away the fluoride left by your toothpaste. Use it at another time of day, such as after lunch, if your dentist or hygienist recommends it.

Some mouthwashes are intended for short-term use and may cause staining or other side effects when used incorrectly. Follow the instructions provided and seek advice if you are unsure which product is suitable.

Reduce How Frequently You Consume Sugar

When bacteria in dental plaque come into contact with sugar, they produce acids that attack the tooth surface. Saliva gradually helps the mouth recover, but repeatedly eating sugary foods creates more frequent acid attacks.

Both the amount and frequency of sugar matter. Eating a sweet item as part of a meal is generally less harmful than consuming small amounts throughout the day.

Try to:

• Keep sweets, cakes and biscuits to mealtimes
• Avoid grazing on sugary snacks throughout the day
• Choose water rather than sweetened drinks for regular hydration
• Reduce sugar added to tea and coffee
• Avoid sugary food and drink after brushing at night
• Check food labels for added sugar

Honey, syrups and sugars found in fruit juice and smoothies can also contribute to decay. Products described as natural or unrefined are not automatically harmless to teeth.

Limit Frequent Acidic Drinks

Acidic food and drink can gradually wear away enamel. This process is known as dental erosion and differs from tooth decay.

Potentially acidic drinks include:

• Regular and sugar-free fizzy drinks
• Fruit juice and smoothies
• Sports and energy drinks
• Wine and cider
• Some flavoured waters

Sugar-free fizzy drinks may reduce the risk associated with sugar, but they can still be acidic. Keep acidic drinks to mealtimes where possible and avoid sipping them over several hours.

Do not swish acidic drinks around your mouth or try to scrub the acid away aggressively. Rinse with water and focus on reducing how frequently the teeth are exposed.

Drink Water Regularly

Still water is the safest drink for regular hydration because it does not expose the teeth to sugar or acid. It can also help clear loose food particles and relieve the discomfort associated with a dry mouth.

Saliva helps protect the teeth, makes speaking and swallowing easier and supports the mouth’s natural recovery after eating. Persistent dry mouth can therefore increase the risk of decay and oral discomfort.

Dry mouth may be associated with medication, dehydration, mouth breathing, anxiety or certain health conditions. Speak to a dentist, GP or pharmacist if it continues. Do not stop taking prescribed medicine without professional advice.

Look After Your Gums

Healthy gums should not regularly bleed when brushed gently. Persistent bleeding, redness or swelling can indicate inflammation caused by plaque around the gum line.

Other warning signs can include:

• Persistent bad breath
• Gums pulling away from the teeth
• Teeth beginning to look longer
• A bad taste in the mouth
• Spaces developing between teeth
• Adult teeth becoming loose

Gum disease may cause little pain in its early stages, so do not wait for significant discomfort before arranging advice.

A dentist or hygienist can assess your gums, identify areas being missed and show you how to control plaque more effectively.

Attend Dental Check-Ups at the Interval Recommended for You

There is no single dental check-up schedule suitable for every patient. Your recommended interval should reflect your current oral health and risk of developing future problems.

Factors that may affect how often you are advised to attend include:

• Your history of tooth decay or gum disease
• The condition of existing fillings and crowns
• Your age and stage of dental development
• Smoking and dietary habits
• Dry mouth
• Certain health conditions or medicines
• Your ability to control plaque at home

Some patients need relatively frequent reviews, while adults with stable oral health may be advised to attend less often. Your dentist should explain the recommended interval and review it when your circumstances change.

A check-up may include an assessment of your teeth, gums, soft tissues and existing dental work. X-rays are only recommended when clinically necessary and are not automatically required at every visit.

More information about examinations and routine treatment is available on the general dentistry page.

Professional Cleaning and Hygiene Support

Even with regular brushing, some people find it difficult to remove plaque from every part of their mouth. Plaque can also harden into tartar, which cannot usually be removed with a toothbrush at home.

A dentist or hygienist can assess your gum health and recommend professional cleaning where appropriate. They can also demonstrate how to clean difficult areas and advise on caring for:

• Crowns and bridges
• Dental implants
• Dentures
• Braces and retainers
• Crowded or overlapping teeth

Professional cleaning is intended to support your home routine rather than replace it. The long-term result still depends on controlling plaque consistently between appointments.

Fluoride Varnish and Fissure Sealants

Some patients may benefit from additional preventative treatments based on their age and risk of tooth decay.

Fluoride varnish is applied to the teeth by a trained dental professional to help strengthen the tooth surface. A higher-fluoride toothpaste may also be prescribed for some patients at increased risk of decay.

Fissure sealants are thin protective coatings placed over the grooves of suitable back teeth. They create a smoother surface that is easier to clean and can reduce the risk of decay developing in vulnerable fissures.

These treatments are not automatically needed by everyone. Your dental team will assess whether they are appropriate and explain the expected benefits.

Protect Your Teeth During Sport

A mouthguard can reduce the risk of injuries to the teeth, lips and surrounding tissues during contact and ball sports.

A properly fitting guard should remain securely in place and allow you to breathe comfortably. Children and teenagers may need replacements as their teeth and jaws develop.

Check the mouthguard regularly and replace it if it becomes damaged, distorted or no longer fits correctly. Speak to a dentist about the available options, particularly if you have braces or existing dental restorations.

Ask About Grinding and Clenching

Grinding and clenching can place excessive force on the teeth. Over time, this may contribute to worn enamel, sensitivity, cracks, damaged fillings, jaw discomfort or headaches.

Many people grind while asleep and may only become aware of it when a partner hears the noise or a dentist notices signs of wear.

A custom-made bite guard may be recommended to protect the teeth in suitable cases. It does not necessarily stop the grinding habit itself, so stress, sleep and other contributing factors may also need to be considered.

Avoid Smoking

Smoking increases the risk of gum disease, slows healing and raises the risk of mouth cancer. It can also stain the teeth and reduce visible gum bleeding, making inflammation less obvious.

Stopping smoking benefits both oral and general health. Your dental team can discuss how smoking is affecting your mouth and direct you towards suitable NHS stop-smoking support.

Do Not Ignore Changes Between Appointments

Preventative care does not mean waiting until your next scheduled check-up when something feels wrong.

Arrange dental advice if you notice:

• Persistent toothache or sensitivity
• Bleeding or swollen gums
• Pain when biting
• A chipped or cracked tooth
• A loose filling or crown
• An adult tooth beginning to move
• A mouth ulcer lasting longer than three weeks
• An unexplained lump, red patch or white patch

Seek more urgent advice for severe pain, facial swelling, significant trauma, uncontrolled bleeding or difficulty swallowing or breathing.
