Fissure Sealants

The Milton Keynes Dental Hygienist Practice offers the full range of Dental Prevention.

Q What are Fissure Sealants?
A Fissure Sealants are a safe and painless way or protecting your children’s teeth from decay. A sealant is a protective plastic coating, which is applied to the biting surfaces of the back teeth. The sealant forms a hard shield that keeps food and bacteria from getting into the tiny grooves in the teeth and causing decay.

Q When should Fissure Sealants be done?
A Sealants are usually applied as soon as the permanent teeth start to come through. This is usually between 6 and 7 years of age. The rest are usually sealed as soon as they appear which can be any time between 11 and 14 years of age.

Q Can Fissure Sealants be done for adults?
A There is usually no reason not to do Fissure Sealants for Adults, and we now do a lot of sealants for older patients where there is a high risk of decay.

Q Which teeth should be sealed?
A Sealants are only applied to the back teeth – the molars and premolars. These are the teeth that have pits and fissures on their biting surfaces. We will tell you which teeth should be sealed after we have examined the teeth, and checked whether the fissures are deep enough for sealing to help.

Some teeth naturally form with deep grooves, which will need to be sealed, others with shallow ones which will not need sealing.

Q What is involved?
A The process is usually quick and straightforward taking only a few minutes per tooth. The tooth is thoroughly cleaned, prepared with a special solution, and dried. The liquid sealant is then applied and allowed to set hard – usually by shining an ultraviolet light onto it.

Q Will my child feel it?
A No, it is totally pain free, and the teeth do not feel any different afterwards.

Q How long do they last?
A Sealants usually last for many years, but we will want to check them regularly to make sure that the seal is still intact. They can wear over time, and sometimes the dentist needs to add or replace some sealant to be sure that no decay can start underneath them.

Q How do they work?
A The sealant forms a smooth, protective barrier, by covering all the little grooves and dips in the surface of the tooth. Normally, and especially with either high sugar intake or poor plaque control, dental decay easily starts in these grooves.

Are all Fissure Sealant treatments the same?


The recent advances in materials and the bonding systems means that the modern sealants are much more durable and they do not leak. Combined with the OZONE the treatment is simply the only way to seal the tooth surface without drilling and doing a filling.

Q How much do Fissure Sealants cost?
A It varies on the size of the tooth and the ease of access but as a guide fissure sealents are between £25 and £35 each

Q Do my children still have to clean their teeth?
A Yes. It is still vital that they do this. The smooth, sealed surface is now much easier to keep clean and healthy with normal tooth brushing. Using a fluoride toothpaste will also help to protect your children’s teeth. Pit and fissure sealing reduces tooth decay and the number of fillings your child might need.

Q Whom do I ask about the treatment?
A If you would like to know more about the treatment, ask the dentist or hygienist. They will tell you if fissure sealing will help your children’s teeth, and if it is the right time to do it.
