Oral health begins even before a child has a full set of teeth. Healthy teeth are essential for eating, speaking, smiling, and proper positioning of permanent teeth. Although baby teeth are temporary, they play a vital role in your child’s overall health and development.
Parents often ask their Paediatricians and paediatric dentists about when to start brushing their baby’s teeth. Dentists believe that oral care should begin much before the first teeth appear to prevent tooth decay, establish healthy habits, and help develop a routine that continues well into childhood.
This article explains when to start brushing your baby’s teeth, how to clean your baby’s mouth at different ages, the best toothbrush and toothpaste to use, common mistakes to avoid, and when to visit a paediatric dentist.
Baby teeth, also called primary teeth or milk teeth, help your child bite and chew food properly, learn to speak clearly, maintain space for permanent teeth, support healthy jaw growth, and develop a confident smile. Early loss of baby teeth due to decay and infection can cause adjacent teeth to shift into empty spaces, causing crowding or alignment problems later.
Before your baby’s first tooth erupts, it’s important to begin oral care to help maintain healthy gums and establish good oral hygiene habits. Good oral care starts before the appearance of the first tooth. Although babies do not have visible teeth, bacteria can accumulate on the gums and tongue. Their mouths should be cleaned regularly, thereby introducing them and making them comfortable with it from an early age.
After feedings or at least once daily:
This simple routine removes milk residue and helps maintain a clean mouth.
Brushing should begin as soon as your baby’s first tooth erupts, typically around 6 months, although it may appear anytime between 4 and 12 months. The lower front teeth typically appear first, followed by the upper front teeth. Once the first infant tooth appears, switch from wiping the gums to using a soft infant toothbrush to gently clean the teeth.
Parents assume that baby teeth cannot develop cavities because they are temporary. However, tooth decay can begin soon after the first tooth erupts. Early childhood tooth decay is a very common chronic disease in children worldwide. Cavities can cause pain, difficulty eating, poor sleep, speech problems, infection, and premature tooth loss. Starting to brush as soon as the first tooth appears helps remove plaque, reduce harmful bacteria, and protect the enamel from decay.
When the baby’s first tooth appears, select a toothbrush designed for infants, soft-bristled, easy for parents to hold, and small enough to fit comfortably in the mouth. Replace the toothbrush every three months or sooner if the bristles become worn. Do not share toothbrushes between family members, as this can spread bacteria. It is advised to use fluoride toothpaste from the time the first tooth erupts.
Use only a tiny amount of fluoride toothpaste—about the size of a grain of rice. This provides cavity protection while minimizing fluoride ingestion. Parents should place the toothpaste on the toothbrush themselves.
Brush your baby’s teeth twice daily—in the morning and before bedtime. Brushing before bedtime is important because saliva production decreases during sleep, allowing bacteria to multiply more easily. If your baby falls asleep immediately after feeding, gently brush the teeth before bedtime whenever possible.
Follow these simple steps:
Do not worry if your baby spits out or swallows the toothpaste, as it is considered safe when used in the recommended amount.
The tongue naturally collects bacteria and milk residue. While brushing the teeth, gently brush or wipe the tongue if your baby tolerates it. Avoid it if it causes gagging or distress.
Teething usually begins at around 6 months and has the following signs:
Continue brushing during teething, even if the gums are slightly tender. To make brushing more comfortable, use gentle pressure, offer a chilled (not frozen) teething ring, and brush slowly and calmly.
The simple answer is yes. Breast milk offers many health benefits; however, cavities can still occur if teeth are frequently exposed to sugars without proper cleaning. After teeth erupt, maintaining regular brushing is important regardless of whether your baby is breastfed or formula-fed.
One of the leading causes of early childhood cavities is prolonged exposure to sugary liquids. Do not put your baby to bed with milk or formula, fruit juice, or sweetened drinks. If your baby needs a bottle at bedtime following teeth eruption, water is the safest option unless otherwise advised by your healthcare provider.
Fluoride strengthens tooth enamel and helps prevent cavities. Most community water supplies contain fluoride at recommended levels. If your household uses well water or bottled water exclusively, ask your paediatrician or paediatric dentist whether your child needs additional fluoride. Do not give fluoride supplements unless recommended by a healthcare professional.
Schedule the first dental visit by the first birthday or within six months of the first tooth erupting. Early visits allow the dentist to monitor tooth development, identify early signs of cavities, discuss feeding and brushing habits, answer parents’ queries, and provide personalized preventive advice.
Some babies resist brushing in the beginning, which is normal.
Try the following tips to ensure brushing is part of their daily routine, as consistency is more important than perfection:
Brushing should begin with the very first tooth. Do not wait until all the teeth appear. Do not use too much toothpaste (a grain-sized amount until age 3). The risk of tooth decay increases when babies are exposed to milk or juice during sleep. Cleaning the teeth before bedtime is a must and should not be skipped. Brushing should be done under parental supervision until age 8 because children do not possess hand coordination to clean teeth effectively.
My baby has no teeth. Do I still need to clean the mouth?
Yes. Gently wiping the gums with a clean, damp cloth helps remove bacteria and introduces your baby to oral care.
What if my baby cries during brushing?
Many babies require time to adjust. However, keep the brushing routine consistent, gentle, and brief. Most children become more comfortable with practice.
Is fluoride toothpaste safe?
Yes. Grain-sized amounts are recommended for infants and considered safe and effective for preventing cavities.
My baby’s teeth look white. Do I still need to brush twice a day?
Yes. Plaque is often invisible. Regular brushing removes bacteria before they can cause decay.
Good oral health starts from birth. Start gently cleaning the gums even before the first tooth appears to help establish healthy oral habits early. Upon the eruption of the first tooth, brush twice daily with a soft infant toothbrush and a grain-sized amount of fluoride toothpaste.
Baby teeth are crucial for nutrition, speech, jaw development, and guiding permanent teeth into place. Early brushing, healthy feeding practices, and regular dental checkups can significantly reduce the risk of cavities and support lifelong oral health.
Parents play a crucial role in their child’s oral health by making brushing a consistent part of the daily routine that gives the child a healthy start that can last a lifetime.
