Why should oral care start early?
Children’s teeth need care from the moment the first primary tooth erupts, because teeth can develop decay as soon as they appear. The American Academy of Pediatric Dentistry recommends establishing an ongoing dental relationship no later than 12 months of age, or within six months of the first tooth erupting. [1] [2]
An early visit is not only a dental examination. It allows the dentist to assess the child’s risk of decay, review brushing technique, discuss feeding and oral habits such as thumb-sucking or pacifier use, and develop an age-appropriate prevention plan.
How can parents care for a child’s teeth at home?
Brush twice a day: Start brushing when the first tooth appears, using a small, soft-bristled toothbrush and fluoride toothpaste. [2] [3]
Use the correct amount of toothpaste: For children younger than 3 years, use a smear about the size of a grain of rice. From 3 to 6 years, use no more than a pea-sized amount, with adult supervision to reduce swallowing. [2] [3]
Help and supervise: Most young children need parental help or supervision because they cannot yet clean every tooth surface effectively.
Limit sugar: Frequent sugary snacks and drinks, particularly between meals and before bedtime, increase the risk of decay. Offer water between meals and limit sweetened drinks and foods. [4]
Do not share mouth-contact items: Parents should avoid cleaning a pacifier or spoon with their own mouth before giving it to a child, as this may transfer bacteria associated with tooth decay.
Keep preventive appointments: The dentist will advise how often the child should be reviewed based on age and decay risk. Fluoride varnish or fissure sealants may be recommended in some cases, particularly when permanent molars erupt. [2] [3]
When should parents arrange a prompt dental appointment?
Contact a dentist if a child has any of the following:
Toothache or recurring pain while eating or drinking.
Sensitivity to cold, hot, or sweet foods and drinks.
White, brown, or black spots on the teeth.
A visible hole or broken tooth.
Painful, swollen, or bleeding gums.
Persistent bad breath together with pain or swelling.
Difficulty chewing or avoiding one side of the mouth.
Continued thumb-sucking or pacifier use that may affect tooth or jaw development; the timing of any intervention should be assessed individually by a dentist. [4]
Decay may not cause symptoms in its early stages, so parents should not wait for pain before seeking care. Regular examinations can identify problems earlier and reduce the risk of progression to pain or infection. [4]
When is urgent care needed?
Seek urgent dental or medical care if the child develops rapid or marked swelling of the face or mouth, swelling extending toward the eye or neck, difficulty breathing or swallowing, or significant illness with fever. Dental injuries, such as a knocked-out or broken tooth after a blow, also require prompt contact with a dentist for specific advice.
Severe or persistent bleeding, or severe pain that does not settle, also requires urgent assessment. Do not place aspirin on the tooth or gums, and do not give medicines unless they are appropriate for the child’s age and weight or have been advised by a healthcare professional.
How can parents make dental visits easier?
Talk about the dentist in a calm and positive way.
Avoid frightening words such as “needle” or “pain” unless the dentist needs to explain a procedure.
Choose an appointment when the child is rested and has eaten appropriately.
Tell the dentist in advance about chronic conditions, medicines, allergies, and any previous difficult experiences.
Do not wait for a painful problem before the first visit. Preventive appointments help children view dental care as a normal part of healthcare. [1] [3]
Key message
A child’s oral health begins at home and with an early first dental visit, preferably during the first year of life. Fluoride toothpaste, limiting sugar, daily supervision, and regular dental reviews help prevent tooth decay. Pain, spots, swelling, or dental injuries should prompt contact with a dentist, while difficulty breathing or swallowing or severe swelling requires urgent care.
