What protects children's teeth most is a mix of three things: fluoride toothpaste in the right amount for their age, eating and drinking habits that reduce how often teeth meet sugar, and simple preventive treatments at the clinic such as fluoride varnish and fissure sealants. These treatments are quick and usually need no drilling or numbing, but they do not replace daily brushing; they add to it.
Fluoride varnish is a sticky coating painted on the teeth with a small brush in a few minutes. It sticks to the teeth and releases fluoride gradually, helping strengthen enamel and stop early decay before it becomes a cavity.
It can start once the first teeth appear and is usually repeated every 3 to 6 months depending on your child's decay risk, as your dentist advises. Afterwards, children are usually asked to avoid hard food and hot drinks for a few hours and to delay brushing until the evening or next morning, as instructed.
The chewing surfaces of back teeth have fine grooves and pits where food collects and toothbrush bristles struggle to reach, so a lot of childhood decay starts there. A fissure sealant is a thin liquid coating placed into these grooves and hardened with a light, leaving a smooth surface that is easier to clean.
It is usually placed on permanent molars soon after they come through: first permanent molars around age 6 to 7, and second molars around 11 to 13. It may also be placed on baby molars in children at high risk of decay. It usually needs no drilling, and it is checked at each routine visit and repaired if part wears away.
Fluoride toothpaste is the most important daily source of protection. The amount should suit the child's age, and brushing should be supervised by a parent:
Decay is not only about the amount of sugar but about how often the teeth are exposed to it during the day. A child who sips juice throughout the day, or falls asleep with a bottle in their mouth, keeps their teeth under constant acid attack.
So do not let your child sleep with a bottle of milk or juice, and make water the drink between meals. Keep sweets to mealtimes rather than spread through the day, and watch out for sticky sweets and biscuits that cling to teeth. During Eid and family occasions, when sweets and stuffed dates are everywhere, make bedtime brushing a rule with no exceptions.
In the summer heat, children may reach for sweetened drinks and boxed juices when thirsty; cold water is a better choice for their teeth and their health.
Fluoride in the recommended amounts is safe and beneficial, and dental health bodies recommend it. Too much fluoride while the teeth are forming, for example if a child regularly swallows large amounts of toothpaste, can cause faint white marks on the permanent teeth known as fluorosis.
So keep toothpaste out of your child's reach and use the right amount for their age. Do not give fluoride tablets or drops unless a dentist or paediatrician prescribes them after reviewing your child's other fluoride sources.
They clearly reduce the risk of decay on chewing surfaces, but they do not protect between the teeth or replace brushing and flossing. Fluoride toothpaste and good habits remain essential.
They can last several years but may partly wear with chewing. Your dentist checks them at routine visits and repairs them when needed.
No. The answer is to reduce the amount to a rice-grain smear for young children and to supervise brushing. Occasionally swallowing this small amount is not usually a concern.
It benefits most children, and children at higher risk of decay have it more often. Your dentist sets the right schedule after an examination.
See a dentist if you notice chalky white spots near the gums, brown or black spots on the teeth, if your child complains of pain when eating or drinking something cold, or if the gums swell. It also helps to arrange a visit when the first permanent molars appear to assess whether sealants are needed.
