My son is 6yrs old. My son developes a black gummy substance buildup on his front teeth in front and behind. He and I brush/floss his teeth every day.  We use a dental pick to remove the substance but it comes back everyday.What is the clinical term for this?.  I would llike to look into this further.  The pediatric dentist said he has seen this in children and adults. Some children outgrow it.  Why does this happen?
Hi, Thanks for posting the query, This could be due to development of dental plague and calculus. I would suggest you to use proper technique for flossing and brushing. Visit to the Dentist and get professional mouth scaling done. Take lukewarm saline and antiseptic mouthwash rinses. Take care!
