How is osteonecrosis of the jaw treated?
Osteonecrosis can either be treated conservatively, or surgically:
i) Conservative treatment
Conservative treatment basically means that no active treatment is done that is directly addressing the problem. Usually, patients who present with osteonecrosis of the jaw are started on antibacterial rinses (eg: Chlorhexidine gluconate mouthwash), antibiotics and oral analgesics. Continue reading

The damage to the jaw bone is irreversible, and if left untreated, can spread and can cause devastating damages, even to the point of death. Continue reading
What is radiation therapy?
