Short answer: Baby bottle tooth decay is rapidly progressing decay in the baby teeth of infants and young children, especially in the upper front teeth; medically, it is called early childhood caries. Giving milk or sugary drinks in a bottle during sleep, frequent and long night-time feedings, and not cleaning the teeth are the main causes. It can largely be prevented by brushing with fluoride toothpaste from the first tooth and regular dental check-ups.
Baby teeth are important structures that hold space for the permanent teeth and support the development of chewing and speech. However, their enamel is thinner than that of permanent teeth and more vulnerable to decay. Baby bottle tooth decay is a pattern of tooth decay seen in infancy and early childhood that often starts in the upper front teeth and can progress quickly. The good news is that it can largely be prevented. In this article, we cover the causes and first signs of baby bottle tooth decay, the protective rules parents can follow and the treatment options.
What is baby bottle tooth decay?
Baby bottle tooth decay is tooth decay seen in the baby teeth of children under six, medically called "early childhood caries." It takes its name from the fact that a bottle left in the mouth during sleep is a common cause; however, the bottle is not the only cause.
It typically starts first in the upper front incisors, in the area close to the gums. The lower front teeth are often affected later, because the tongue covers these teeth during sucking and they are close to the salivary glands. Untreated decay can also spread to the molars and lead to pain, infection and early tooth loss. Baby teeth lost early can cause the loss of the space needed for the permanent teeth and lead to orthodontic problems later on.
Causes: night-time bottles and sugary drinks
The main cause of baby bottle tooth decay is the teeth being in contact with sugary liquids for long periods and at frequent intervals without being cleaned in between. Bacteria in the mouth convert sugars into acid; this acid causes mineral loss from the tooth enamel.
- Bottle during sleep: Saliva flow decreases during sleep. When the baby falls asleep with a bottle of milk, formula, fruit juice or a sugary drink, the liquid stays around the teeth for a long time.
- Frequent and long night-time feedings: Once teeth have erupted, frequent feeding throughout the night without cleaning the teeth afterwards can increase the risk.
- Fruit juice and sugary drinks: Fruit juice, sweetened tea or ready-made drinks sipped throughout the day from a bottle or sippy cup keep the teeth constantly in an acidic environment.
- Dipping the pacifier in honey, sugar or jam: This habit directly raises the risk of cavities. Giving honey to babies under one year of age is also not recommended for health reasons.
- Bacteria transmission: Cavity-causing bacteria can pass to the baby through sharing spoons or "cleaning" the pacifier with the parent's mouth.
- Lack of fluoride and inadequate oral care: Not brushing the teeth regularly and not using fluoride toothpaste leaves the enamel unprotected.
What are the signs?
The first sign of baby bottle tooth decay is dull, chalky white spots or lines on the upper front teeth near the gums. At this stage, the enamel has started to lose minerals, but a cavity may not have formed yet. This period is a valuable opportunity when the decay can be stopped and even reversed.
As the decay progresses, the following signs may be seen:
- The spots turning yellow, brown or black,
- Breaking, chipping or visible holes in the teeth,
- Fussiness with hot, cold or sweet foods and avoiding eating,
- Night-time waking and unexplained fussiness,
- Swelling of the gums, a pimple-like bump or a bad smell (which may be a sign of infection).
If there is toothache together with facial swelling or fever, you should see a dentist or an emergency health facility without waiting.
How can baby bottle tooth decay be prevented? Rules for breastfeeding, bottles and care
The most effective way to prevent baby bottle tooth decay is to start oral care before the first tooth and to arrange feeding habits in a way that protects the teeth. The following recommendations are in line with the general recommendations of international pediatric dentistry organizations:
- Before teeth erupt: After feedings, wipe the baby's gums with a clean, damp gauze pad or a soft cloth.
- Brushing from the first tooth: As soon as the first tooth appears, start brushing twice a day with a soft baby toothbrush and a rice-grain-sized amount of fluoride toothpaste. After age three, the amount can be increased to the size of a pea. Night-time brushing is especially important.
- Do not put the baby to bed with a bottle: If the baby falls asleep with a bottle, it should contain only water. Finish milk or formula feeding before sleep and clean the teeth.
- Switching to a cup: Switching to a cup is generally recommended around the first birthday. Using sippy cups with sugary drinks throughout the day carries a similar risk.
- Limit fruit juice: Fruit juice is not recommended for babies under one year of age; for older children, it is appropriate to give it in limited amounts and with meals, not in a bottle. Whole fruit is a better option.
- Reduce snacking frequency: The risk of cavities depends not only on the amount of sugar but also on how many times the teeth come into contact with sugar. Setting specific meal and snack times instead of snacking nonstop throughout the day gives saliva time to neutralize the acid. Foods that stick to the teeth, such as biscuits, crackers and dried fruit, need as much attention as sugar.
- Do not sweeten the pacifier and do not clean it with your mouth; avoid sharing spoons.
- Early dental visit: It is recommended that the first dental check-up take place after the first tooth erupts and at the latest around the first birthday.
Breast milk is valuable for the baby's health, and these recommendations do not mean stopping breastfeeding. Once teeth have erupted, you can work out a routine that suits your family regarding the frequency of night-time feedings and oral cleaning afterwards by talking to your pediatrician and dentist.

What are the treatment options?
Treatment of baby bottle tooth decay is determined by how far the decay has progressed and the child's age; when caught early, it can be controlled with simpler methods.
- Early spots: At the white spot stage, the progression of decay can be stopped with fluoride varnish applied by the dentist, improved oral care and changes in eating habits.
- Fillings: In teeth where a cavity has formed, the decayed tissue is removed and the tooth is restored with a suitable filling material.
- Root canal treatment (pulp treatment in baby teeth): Can be done to preserve the tooth when decay reaches the nerve.
- Crowns: Baby teeth with a lot of tissue loss can be protected with prefabricated crowns made for children.
- Extraction and space maintainer: Teeth that cannot be saved are extracted; if deemed necessary, a space maintainer is made to preserve the space for the permanent tooth.
When many teeth are affected and the child cannot cooperate with treatment in the chair because of their age, treatment under sedation or general anesthesia may be considered. This decision is made together with the relevant doctors after evaluating the child's general health. Whatever the treatment, if eating and care habits do not change, the risk of new cavities continues.
When should you see a dentist in Ankara about your child's teeth?
If you have noticed white or brown spots on your child's front teeth, if their teeth are chipping or if they get fussy while eating, an early examination helps keep treatment simpler. Even if you do not see a problem yet, planning the first dental visit around the first birthday is a good habit. At our clinic near Panora Mall in Çankaya, oral health evaluations are carried out for our young patients and parents are given guidance on home care.
Frequently asked questions
Is baby bottle tooth decay caused only by bottles?
No. Although its name comes from the bottle, frequent consumption of sugary drinks from a sippy cup, a sweetened pacifier, frequent night-time feedings after teeth erupt and not cleaning the teeth can also lead to the same pattern. What matters is how often and how long the teeth are in contact with sugar.
When should I start brushing my baby's teeth?
It is recommended to start brushing as soon as the first tooth erupts. A soft baby toothbrush and a rice-grain-sized amount of fluoride toothpaste can be used twice a day. Wiping the gums with a damp cloth before teeth erupt is also helpful.
Baby teeth will fall out anyway, so should decay be treated?
Yes, it should be treated. Decayed baby teeth can lead to pain, infection and feeding problems. Baby teeth lost early can cause the permanent teeth to lose their space and lead to tooth alignment problems later on.
When should I take my child to the dentist for the first time?
The general recommendation is for the first dental visit to take place after the first tooth erupts and at the latest around the first birthday. This visit is helpful both for catching early signs and for guiding parents on care.
