Hello doctor,

My daughter is a 4-year-old, and her tooth was paining and became different in color. We consulted with a dentist, and she said the tooth was infected by bacteria due to breast or bottled milk. Half of the tooth is decayed, and she has pain. Is there a need to fill some paste in it and put artificial teeth over it? Is it the only option? Kindly suggest.



Welcome to

The condition your child is having is called early childhood caries. It is common in children between two and five years, where the upper front teeth are most commonly affected. However, extraction is advised if the child has a severe infection with inflammation and pus from the tooth. Ensure you maintain the child's oral hygiene with thorough rinsing after every meal, even after snacking with water. Mouth rinses like Kidodent (Sodium fluoride, Triclosan, and Xylitol) mouthwash will aid as well. Do not worry. Restoration of the infected tooth will help her troubles as it will aid in preventing the further spread of infection, which, if not controlled, may infect her permanent tooth. I hope this answers your query.

Thank you.
