No, you should not be worried if your 10-month-old has 10 teeth, as this is within the normal range of tooth development for infants. Most babies begin teething around 6 months of age, with the lower central incisors typically appearing first, followed by the upper central incisors. By 10 months, it's common for babies to have between 2-8 teeth, but some develop teeth more quickly and may have 10 teeth by this age. Every child develops at their own pace, and the timing of tooth eruption varies considerably among infants. Genetics plays a significant role in determining when teeth appear. As long as your baby is developing normally in other ways and the teeth appear healthy, having 10 teeth at 10 months is not a cause for concern. Some key points to consider in relation to your baby's teeth include:

  • The importance of early dental hygiene practices, such as gently cleaning your baby's teeth with a soft infant toothbrush and a tiny smear of fluoride toothpaste (about the size of a grain of rice) twice daily 1.
  • The need for regular dental check-ups to monitor the health of your baby's teeth and prevent any potential issues, such as dental caries 2, 3.
  • The role of good oral hygiene and dietary habits in preventing dental caries, including limiting sugary foods and drinks and promoting a healthy diet 4, 5. It's always a good idea to consult with your pediatrician or a pediatric dentist if you have any concerns about your baby's teeth or overall oral health. They can provide personalized advice and guidance to help ensure your baby's teeth and mouth remain healthy.
