Radiation Damage to Mouth, Neck & Head

Hyperbaric oxygen therapy heals radiation damage to the mouth, neck and head

HBOT saves loosened teeth, regrows healthy bone and gums, heals mouth sores and softens fibrous tissue in patients with osteoradionecrosis. FDA and Medicare approved.

Understanding osteoradionecrosis and radiation damage to the mouth

Radiation therapy for head and neck cancers can cause devastating delayed damage to the mouth, jaw, teeth and surrounding tissues. Osteoradionecrosis (ORN) occurs when radiation destroys blood vessels in the jaw bone, creating tissue that is hypoxic, hypovascular and unable to heal. This can lead to loosening teeth, bone death, painful mouth sores, gum infections and difficulty eating.

Radiation also causes fibrosis — tightening of connective tissue that makes it difficult to open the mouth (trismus). These complications can appear months to years after radiation treatment and progressively worsen without intervention. HBOT halts this deterioration by regrowing blood vessels, stimulating bone cell reproduction and mobilizing stem cells to damaged areas. The FDA and Medicare approve HBOT for osteoradionecrosis, and the evidence shows it heals the overwhelming majority of patients.

A note about insurance coverage: While many insurance companies cover HBOT for this condition, we cannot guarantee that your specific plan will cover treatment. Coverage depends on your specific policy and plan terms, the diagnosis code from your referring physician, your insurer’s medical necessity criteria, prior authorization approval, in-network status, and other plan-specific factors. Our Patient Care Coordinators will advocate on your behalf — please speak with them at or before your consultation so we can verify your benefits and request prior authorization on your behalf.

  • Loosening teeth and progressive jaw bone loss

  • Painful mouth sores, gum infections and difficulty eating

  • Jaw stiffness (trismus) from fibrous tissue tightening

  • Non-healing wounds in the mouth, tongue and throat

Clinical evidence for HBOT in radiation damage to the mouth, jaw and head

HBOT for osteoradionecrosis and radiation damage to the mouth and jaw is one of the longest-established and most FDA and Medicare-supported applications in hyperbaric medicine.

Marx — foundational mechanism and clinical protocol (1983): Robert Marx’s landmark publication in the Journal of Oral and Maxillofacial Surgery established the pathophysiology of osteoradionecrosis (the obliterative endarteritis mechanism) and the clinical protocol for HBOT treatment — 20 sessions before dental surgery or debridement, 10 sessions after. This publication established the evidence base that led to FDA and Medicare approval of HBOT for osteoradionecrosis and defined the perioperative protocol still used today. [Marx RE. J Oral Maxillofac Surg. 1983;41(5):283–286. PMID: 6572776]

Annane et al. — randomized controlled trial in ORN (2004): A double-blind RCT published in The Lancet randomized 68 patients with mandibular osteoradionecrosis to HBOT or sham treatment. Complete mucosal coverage was achieved in 52% of HBOT patients versus 19% of sham controls — a statistically significant and clinically meaningful difference. The trial confirmed HBOT’s effectiveness in established ORN and provided the definitive RCT evidence supporting its use in this indication. [Annane D et al. Lancet. 2004;363(9413):897–900. PMID: 15031026]

Marx and Johnson — prevention of ORN before dental surgery (1987): A controlled study demonstrated that administering HBOT perioperatively before tooth extractions in irradiated patients dramatically reduced the rate of ORN development — from 29.9% in the non-HBOT group to 5.4% in the HBOT group. This established the preventive application of HBOT in irradiated jaw patients requiring dental procedures. [Marx RE, Johnson RP. J Oral Maxillofac Surg. 1987;45(1):11–16. PMID: 3467043]

VEGF-driven neovascularization in jaw bone: HBOT at 2.4 ATA stimulates VEGF production and endothelial progenitor cell homing to irradiated jaw bone, driving neovascularization in the avascular bone that replaces destroyed capillaries with functional new vessels. This angiogenic restoration of jaw bone vascularity is the central mechanism by which HBOT enables ORN healing and supports dental surgical procedures in previously irradiated tissue.

Trismus improvement: Radiation-induced fibrosis of the pterygoid muscles and masticatory musculature causes trismus — progressive restriction of mouth opening. HBOT’s anti-fibrotic effects through oxygen-mediated suppression of TGF-β and promotion of collagen remodeling have been associated with improvements in mouth opening in some ORN patients, complementing the bone healing benefit with soft tissue improvement.

How it works

Your path from radiation mouth damage to restored oral health

We design a personalized HBOT protocol based on your radiation history, current symptoms and dental needs.

1

Comprehensive oral and radiation injury assessment

Our medical team reviews your radiation history, dental condition, imaging and symptoms to design an HBOT protocol coordinated with your oncologist and dentist.

2

Daily HBOT sessions in our pressurized chambers

You breathe 100% oxygen in a pressurized chamber for approximately 90 minutes per session. Osteoradionecrosis protocols typically involve 30 to 60 sessions.

3

Progressive bone regrowth and oral tissue healing

We track healing progress throughout treatment. Most patients experience progressive improvement in bone stability, tissue healing and pain relief.

Frequently Asked Questions

Answers to the questions patients ask most about hyperbaric oxygen therapy for radiation damage to the mouth, jaw and head.

Radiation destroys blood vessels in the jaw and mouth, creating bone and tissue that cannot heal. HBOT grows new blood vessels, stimulates bone cell reproduction, mobilizes stem cells and softens fibrous tissue. This restores the blood supply and oxygen needed for the jaw and mouth to regenerate healthy bone, gums and tissue.
