Hi. Anyone any experience of ANUG or pericoronitis please? After a spell of ill health my son has developed both and is pretty unwell. On antibiotics and dentist has told him hemust scrub his teeth and gums very hard! I can't quite believe that this won't just cause more trauma and questioned the dentist but he is adamant he must. I know dental hygiene is so important but am doubting this practitioner.Any thoughts or advice please?Thanks so much.
