Study Arms:
- 3D printed stent+ MDASI-3D Oral Stents Questionnaire (Type: OTHER): Patients wear a customized 3D printed oral stent over 5-10 minutes in the supine position at the time of radiation simulation, before starting radiation therapy, and in the 3rd to 5th week of radiation therapy. Patients may also optionally wear the commercially-made stent called TruGuard at these timepoints. Ancillary Studies (MDASI-3D Oral Stents Questionnaire)
