Oral Hygiene

How I can help the child develop a healthy mouth after years of poor oral hygiene?
I have only in foster care, and I have given a temporary location.'s a good boy, aged 14, but he has lived strictly soft drinks for years. Has not been brushing teeth years, and gums are in very poor condition. In addition to brushing their teeth there anything I can do to help you improve your oral hygiene? Your gums bleed Often something to stop this? etc etc. Thanks in advance.
The right thing to do would be to take the dentist to repair the cavities may be present. Could have chronic abscess may be painless so the only way to ensure that no work would be necessary restrorative X-ray and a careful examination by a dentist. The bleeding of the gums that we are talking about is the gingivitis and has most likely advanced beyond the point of simple brushing and flossing can help. He need a professional cleaning by the hygienist to remove any stones that may be present. Only after all these things are handled can have optimal oral health.
