Fissure Sealants

Get the Flash Player to see this player.

Deep pits and grooves can be found on the chewing surfaces of the back teeth. Such pits and grooves are termed ‘fissures’ and are usually so narrow that toothbrush bristles and streams of water are not able to clean them effectively. These form a favourable environment for bacteria to flourish, often resulting in tooth decay.

What can be done?

Fissure sealants can be applied to the teeth. Fissure sealants are special materials used by dentists to seal off pits and fissures from the oral environment. Sealing the tooth surface protects fissures from bacteria and fermentable foods like sugar and starches to prevent decay from starting deep within the fissures. Any tooth with pits and fissures can be treated, provided the surface to be filled is sound and has not been previously filled. The most commonly treated teeth are the molars and premolars.

How are sealants applied?

Sealants are applied easily and painlessly. No drilling is required. The tooth is properly cleaned, treated, dried, and the sealant applied. It then hardens to form a protective coating over the tooth.

How effective are sealants and how long can they last?

Many studies show sealants to be very effective in preventing decay in fissures. They do, however, require regular maintenance by your dentist. This can be performed with your six- monthly check-up. Recent studies show that a properly placed sealant will last as long as a typical amalgam filling. Even if a sealant is damaged or lost, it is easily repaired and replaced. Regular maintenance by your dentist will help them last. This can be done with your six-monthly check-up.

When should sealants be put on the teeth?

Sealants are most effective when applied after the eruption of the tooth. Early application ensures pits and fissures are sealed before the decay process begins.

To our Patients of NW London Smile Centre,

Our team have been working tirelessly to keep our Dental Practice a safe environment for you. As a Dental Practice, we work in an environment where the prevention of the spread of a whole range of infections is woven into everything we do. In addition to our usual meticulous cross infection measures, we have been paying particularly close attention to all government guidance and updates related to the COVID-19 outbreak.

Given the unprecedented situation in the UK, we feel it is essential that we do our part to reduce the spread of this virus and so. it is with very heavy hearts that we have taken the decision to postpone all routine examinations, treatments and hygiene appointments. This is not a decision we have taken lightly but we feel it is our responsibility to protect you, our valued patients, our team and all our families.

However, looking after the health of our patients is our absolute priority and so we will be maintaining a remote telephone service advice for emergencies only; these include:

  • Severe pain for over 48 hours
  • Facial Swelling
  • Trauma and uncontrolled bleeding

Should you have any of those above please contact our telephone triage service on 07702 207 233

We understand this is inconvenient and it may mean outstanding treatment timelines are extended but we will reconvene normal service as soon as it is safe to do so. If your appointment needs to be postponed, one of our team will be in touch shortly.

Thank you for all your support during these uncertain times.

Please stay safe, please stay at home and we look forward to seeing you all soon!
