Professional fluoride treatment that strengthens enamel and helps prevent decay at Align Dental Surgery

Fluoride treatment

Fluoride treatment

A quick, simple treatment that strengthens tooth enamel and helps keep cavities at bay, useful for children and for anyone with a higher decay risk.

What fluoride does

Fluoride is a natural mineral, found in soil, water and some foods, and added to most toothpastes and many mouth rinses. When it reaches the teeth, it strengthens the enamel, the hard outer layer that protects against decay.

It can also remineralise areas of enamel that have started to weaken, reversing very early decay before it becomes a cavity.

Fluoride in your toothpaste

Fluoride is added to most toothpastes and many mouth rinses, so brushing with a fluoride toothpaste protects your enamel every day between professional treatments.

Why a professional treatment helps

Even with regular brushing and flossing, the bacteria in our mouths produce acids that gradually wear down enamel.

A professional fluoride treatment adds an extra layer of protection against those acids, and helps repair small areas of damage before they grow into larger cavities that need more extensive treatment.

Who benefits most

Fluoride treatment is beneficial for people of all ages. Children benefit most because their teeth are still developing and are more prone to decay, and anyone with a history of decay or a condition that raises their risk can benefit too.

Especially helpful for

  • Children, whose developing teeth are more prone to decay
  • Anyone with a history of frequent cavities
  • People with dry mouth or certain medical conditions that raise decay risk
  • Patients with exposed root surfaces or early white-spot lesions
  • People in orthodontic treatment, where cleaning is harder

Fluoride for children

Children gain the most from fluoride because their enamel is still developing and more prone to decay, so regular application helps guard the new teeth as they come through.

How the treatment works

Fluoride can be applied as a gel, foam or varnish. In the clinic, we use a high-concentration gel or foam applied during a routine visit.

What to expect

  1. Your dentist applies the fluoride gel or foam to the teeth using a small tray or a brush.
  2. It is left on the teeth for at least one minute so it can work into the enamel.
  3. The gel or foam is then rinsed off, and the whole application takes only a few minutes.

Ask about it at your visit

Fluoride treatment is a simple, quick step that helps strengthen and protect teeth from decay, especially in areas that are more prone to cavities.

We usually offer it as part of a check-up. If it has not come up at your visits, ask whether it would help you. It does not replace daily brushing with a fluoride toothpaste and flossing. It adds protection on top.

Questions & answers

Fluoride treatment: common questions

Is professional fluoride treatment safe?
Yes. A professional fluoride treatment uses a controlled, high-concentration product applied for a short time by your dentist, which is safe and well established for both children and adults. The treatment takes only a few minutes, and you are usually asked not to eat or drink for about 30 minutes afterwards so the fluoride can keep working. As with anything, fluoride is used in appropriate amounts, which is exactly why having it applied professionally is sensible rather than relying on guesswork. If you have any concerns, raise them with your dentist and we will explain how it works for your situation.
How often should fluoride treatment be done?
For many people, a fluoride application once or twice a year, as part of a routine check-up, is plenty. Those at higher risk of decay, including some children, people with a history of cavities, dry mouth, or exposed roots, and patients in braces, may benefit from it more often, which your dentist will recommend based on your situation. It is not a replacement for daily brushing with a fluoride toothpaste and flossing; it is an extra layer of protection on top. If fluoride has not been part of your visits, just ask whether it would help you.
Can children have fluoride treatment?
Yes, and children are among those who benefit most, because their teeth are still developing and are more vulnerable to decay. A professional fluoride varnish is quick and gentle, which makes it easy for young patients to tolerate, and it works well alongside good brushing habits and a sensible diet. We will also use the visit to apply sealants where useful and to keep an eye on how the teeth and jaws are developing. See our children's dentistry page for more on how we look after younger patients.
