Many young children are fed by a feedingbottle with lemonade or fruit juice. This can be bad for their teeth. Drinking like this give more chance for development of carries. Parents can teach them using a cup or glass for drinking. It will reduce the possibility of feedingbottle caries.
Permanent teeth sometimes have deep grooves which can be difficult to clean with a toothbrush. At those places can develop carries. A dentist will recommend protecting these teeth with sealants. A sealant is a layer of liquid composite resin.
