Dental Care for the First Teeth: How and When to Start Brushing a Baby's Teeth

The appearance of the first tiny white tooth is a huge event in a family's life and an important milestone in a baby's development. Along with the joy and pride for the little one, parents get a flood of questions: "When should we start brushing?", "Which brush and toothpaste to choose?", "What if the child resists?". It is important to understand that oral care should begin long before the first tooth erupts, and the health of primary teeth is the foundation for the health of permanent ones. Forming proper hygiene habits from early childhood is the best contribution to your child's future healthy and beautiful smile.

When to start? Even before the first tooth appears (0‑6 months)

Oral care should begin before you see the first tooth. This helps remove milk or formula residue, clean the gums, and prepare the baby for the upcoming tooth‑brushing routine.

  • What to do: 1‑2 times a day, for example after the morning feeding and before bedtime, gently wipe the gums, tongue, and the inner surface of the cheeks.
  • What to use: A soft, clean gauze pad or a special silicone teether, dampened with warm boiled water.
  • Why it matters: It is not only hygiene but also a way to accustom the child to oral manipulation. The baby will get used to these sensations, making the later introduction of a toothbrush much easier.

The first tooth has erupted! (Approximately 6‑10 months)

As soon as the first white speck appears over the gums—time to pick up the first toothbrush! Even a single tooth can already be attacked by caries‑causing bacteria. How to get through this challenging period is described in our article "Teething: symptoms and ways to help".

Choosing the first brush and toothpaste:

  • Toothbrush: Choose a special infant brush (marked 0+). It should have a very small head, ultra‑soft bristles, and a comfortable, non‑slippery handle. A silicone teether brush can be an alternative.
  • Toothpaste: With the emergence of the first tooth, modern dental associations recommend starting to use a child’s toothpaste **with fluoride**. Fluoride is the most effective agent for caries prevention.
    • Fluoride concentration: For children up to 3 years old, choose a paste with 500 ppm fluoride (this information is listed on the packaging).
    • Amount of paste: Use the minimal amount—about the size of a **grain of rice**. This dose is completely safe even if the child swallows it.

Brushing technique: how to do it correctly

Brush a baby’s teeth **twice a day**: in the morning after the first feeding and in the evening before sleep, after the last feeding.

  1. Find a comfortable position. The easiest way is to have the child sit on your lap with the head resting on your forearm. This gives you a clear view of the whole oral cavity.
  2. Apply the toothpaste. Squeeze onto the brush an amount the size of a grain of rice.
  3. Brush gently. With soft, "sweeping" motions clean all surfaces of each tooth—outer, inner, and chewing surfaces. Also gently clean the gums and tongue.
  4. Turn it into a game. Sing songs, recite rhymes, use toys. Your goal is to create a positive association with tooth brushing.

What to do if the child resists brushing?

This is a common problem. Be patient and consistent.

  • Brush together. Lead by example.
  • Let the child "brush" you.
  • Allow the child to play with their own brush (under supervision).
  • Don’t give up. Even if the child cries, a few quick yet effective brush strokes are necessary. Consistency and routine will eventually overcome resistance.

Prevention of "bottle" caries

"Bottle" caries is an aggressive form of decay that affects the front teeth and develops from prolonged contact of teeth with sugary drinks.

  • Never let a child fall asleep with a bottle that contains anything other than water (milk, formula, juice, compote).
  • After the evening feeding and brushing, give the child nothing but water.

First dental visit

It is recommended to schedule the first "introductory" visit to a pediatric dentist within 6 months after the first tooth erupts, but no later than the child's first birthday. This helps the child become comfortable with the dentist and receive important preventive advice.

Healthy primary teeth are not only a beautiful smile but also a guarantee of proper jaw development, speech development, and the health of permanent teeth. Your daily care from the first months of life is the best investment in the future.
