A dentist exists to keep the mouth functional, comfortable, and healthy for a\nlifetime — to let people eat, speak, and smile without pain or shame — in a part\nof the body that, once damaged, does not heal itself the way skin or bone does.\nEnamel is the hardest tissue in the body and the only one that cannot regenerate;\na cavity does not get better, and a missing tooth does not grow back. The\ndiscipline exists because the mouth is a high-stakes, low-tolerance environment —\nmillions of bacteria, constant mechanical load, irreversible tissue — and because\nmost dental disease is preventable but, untreated, marches in one direction\nonly: toward pain, infection, and loss.

Stay as high as\n the disease allows.\n- **Preserve tooth structure.** Every cut is permanent. The most conservative\n treatment that solves the problem is almost always the right one.\n- **You can't restore your way out of a disease problem.** A perfect filling in a\n mouth with active decay or untreated gum disease will fail. Control the disease\n first.\n- **Occlusion is destiny.** How the teeth meet drives the long-term fate of every\n restoration; get the bite wrong and even beautiful work breaks down.\n- **Manage the pain and the fear first.** A patient in pain or terror cannot\n consent well or heal well; comfort is the gateway to care.\n- **Diagnose before you treat.** Drilling on a guess turns a small problem into an\n irreversible mistake.\n- **Tell the truth about the tooth.** Patients deserve to know the real prognosis,\n including when the honest answer is \"this tooth is not worth saving.\"","html":"A dentist leads a small clinical team — hygienists who own prevention and\nperiodontal maintenance, dental assistants, and a front office — and refers\nacross a network of specialists: endodontists for hard root canals, oral surgeons\nfor extractions and implants, orthodontists, periodontists, and prosthodontists\nfor complex reconstruction. Outward, the dentist coordinates with physicians on\nmedically complex patients (anticoagulants, bisphosphonates, diabetes) and is\noften the first to spot a systemic disease or refer a suspicious lesion to an\noncologist. The friction lives at the referral boundary — knowing the limits of\none's own skill and when a case belongs to a specialist — and in leading a team\nwhose prevention work makes the dentist's restorative work last.
