When to see a dentist
Schedule a visit if you have tooth pain, bleeding gums, sensitivity to hot or cold, or a chipped or broken tooth. Even without symptoms, routine checkups every six months help catch cavities, gum disease, and oral cancer early when treatment is simpler and cheaper.

Common reasons to see a dentist in Ontario, CA
Tooth pain and sensitivity
Sharp or lingering pain when eating hot, cold, or sweet foods usually means a cavity, cracked tooth, or worn enamel. Your dentist can identify the source with an exam and X-rays and recommend the simplest treatment that solves the problem.
Cavities and tooth decay
Cavities are areas of permanent damage in the hard surface of your teeth. Caught early, they require a simple filling. Waiting until pain appears usually means the decay has reached deeper layers and treatment becomes more involved.
Gum disease and bleeding gums
Red, swollen gums that bleed when you brush or floss signal early gum disease. A professional cleaning and better home care often reverse it, but advanced cases need deeper treatment.
Chipped or broken teeth
A chipped tooth can range from a minor cosmetic issue to a dental emergency depending on the severity. Your dentist will assess whether bonding, a crown, or a referral to a specialist is the best path forward.
Bad breath
Chronic bad breath (halitosis) is often caused by bacteria buildup, gum disease, or dry mouth rather than what you ate for lunch. A dental exam can identify the underlying cause and get you to a solution.
