Dear Doctor, My son will be almost 11 in coming August.  He has bad breath inspite of brushing his teeth twice a day.  Also sometimes while brushing teeth bleeds.  We consulted a dentist and he recommended scaling and also advised to apply quadragel for 4 days to take care of gingivitis.  This was done 2 weeks ago but the problem still persists.  Please help. Thanks Leena
With your query, generally bleeding from gums is due to inflammation of gingival because of accumulation of plaque/calculus/food debris. In your case you have already visited your dentist and the primary treatment was done so nothing to worry. I would suggest you to visit periodontist specialist to rule out the exact cause. Since your son 11 yr old we cannot suspect any systemic complications/disease but is your son having any food regurgitation since bad breath is due to many reasons no need of any local factors it could be systemic diseases like ENT problems/sinusitis/ liver and kidney diseases etc.... so kindly if no systemic diseases are not present then thoroughly get his teeth checked for any pockets or periodontal diseases. Hope this helps you.
