Fissure sealants are thin protective coatings applied to the chewing surfaces of molars to stop decay starting in the grooves. Our dentists provide them at our Primrose Hill practice. A consultation tells us which teeth would benefit and how long the sealants are likely to last for your child.
Our clinical team is led by Dr Ope Sodeinde, GDC-registered specialist periodontist (GDC No. 104071).

The chewing surfaces of back teeth have deep grooves that trap food and bacteria, and a toothbrush bristle often cannot reach the bottom of them. That makes molars the most common place for tooth decay to start in children. Dental sealants fill the grooves so there is nowhere for plaque to hide. They are part of the paediatric dentistry in London we provide across a child's development.
We use dental x-rays where we need to check between teeth, and we teach the brushing habits that keep plaque off the rest of the tooth.
Sealants are simple, but they still need to be the right choice for the tooth. Our dentists, with the practice led by Dr Ope Sodeinde, examine each molar before recommending anything, and you see an itemised plan before any work begins.
Where a groove already shows early decay, we decide together whether a sealant or silver diamine fluoride is the better option. Once sealants are placed, our children's dental aftercare guide explains how to look after them.

Sealants suit children whose molars have deep grooves, and are usually placed soon after the adult molars come through. They are a routine step, often done alongside children's dental exams and cleanings. Some children are anxious about the dentist and some parents worry about their child's dental history; we keep the visit calm and start from where things are now. Sealants are planned prevention, distinct from the urgent care we provide for children's dental trauma. A consultation confirms whether your child's teeth are suitable.
We examine the teeth for deep grooves where plaque collects and decide which molars need sealing. We can also discuss dental hygiene for children and teens at the same visit.
The tooth is cleaned and dried so the sealant bonds to the enamel. There is no drilling and no injection.
We flow a thin resin into the pits and fissures and set it with a curing light. The result is a smooth surface that is easier to keep clean.
We check the coating sits flush with the biting surface so it does not interfere with the bite, and look for any gaps in coverage.
We explain how to look after the sealants with normal brushing, and check them at routine visits. For other developmental concerns, we also provide tongue and lip tie treatment.
Our clinical team provides children's dental exams, cleanings and fluoride treatments alongside sealants.
Where a tooth is already damaged, our dentists repair it with tooth-coloured composite resin, using conservative bonding where that is enough.
We keep visits calm and unhurried, give honest options and never pressure a family into treatment. If a tooth already has a cavity, we provide children's fillings to restore it.

A thin protective coating applied to the chewing surfaces of the back teeth. It fills the deep grooves where food and bacteria collect, leaving a smooth surface that is easier to clean. We can combine sealants with fluoride treatments for added protection.
The cost is confirmed at the clinical assessment, once we know how many teeth need sealing.
That depends on your child's chewing and brushing. We check the sealants at each recall visit and top up any that have worn.
Our dentists choose the material to suit the tooth, and confirm it at the assessment.
Our dentists assess each child to decide whether sealants are the right choice for their molars. Read what happens at your child's dental consultation and how to book to discuss a preventive plan.

Sealants work best alongside children's dental exams and cleanings, dental hygiene for children and teens, and fluoride treatments. If decay has already started, we offer silver diamine fluoride or children's fillings. Our children's dental aftercare guide covers home care.
After the assessment you receive a written plan and an itemised quote for your child, which is yours to keep. Arrange your assessment with the team. Payment options can be discussed with staff.
