Dental disease: Causes, prevention, and simple treatments

Tooth decay and gum disease are the two most common dental problems. They start quietly and get worse fast if you ignore them. This page explains what causes dental disease, simple ways to prevent it, and basic treatment steps you can expect at the dentist.

Common dental diseases

Cavities (tooth decay) form when plaque bacteria eat sugars and damage enamel. Gingivitis causes red, swollen gums that bleed when you brush. If untreated, gingivitis can become periodontitis, which destroys the tissue and bone that hold teeth in place. Dental abscesses are painful pockets of infection that need fast care. Erosion from acid and tooth wear from grinding also lead to lasting damage.

How do you spot a problem early? Look for tooth sensitivity, persistent pain, gums that bleed or pull away from teeth, bad breath that won’t go away, and loose teeth. Any sore in the mouth that lasts more than two weeks needs a dental check.

Prevention and when to see a dentist

Prevention is mostly daily habits. Brush twice a day with fluoride toothpaste and use floss or interdental brushes once daily. Cut back on sugary snacks and acid drinks. Drink water after meals to wash away food and sugar. If you smoke, quit — tobacco raises your risk for gum disease and oral cancers. Use a mouthguard if you grind your teeth or play contact sports.

See a dentist if you have ongoing pain, swelling, fever with a toothache, pus, or a loose tooth. Also make regular checkups every six months or as your dentist recommends. Early treatment saves money and prevents tooth loss.

What treatments can help? Small cavities often need a filling. Deeper infection may require root canal treatment or extraction. Gingivitis is treated with better home care and professional cleaning. Periodontitis needs a scaling and root planing session and sometimes surgery. Dentists can replace missing teeth with bridges, implants, or dentures depending on your needs.

At home, use warm salt rinses for short-term pain relief and to reduce swelling. Avoid using sharp objects on your teeth. For pain, acetaminophen or ibuprofen can help until you see a dentist. Don’t rely on home remedies to fix an infection — antibiotics and dental work may be necessary.

Certain health conditions and medicines change your mouth. Diabetes makes infections worse and slows healing, so control blood sugar and tell your dentist. Pregnancy can cause extra gum swelling — keep clean and get care. Many common drugs cause dry mouth, which raises decay risk; ask your doctor about saliva substitutes or sugar-free gum. When dentistry and medicine overlap, share your full health list.

Keeping teeth and gums healthy is a daily job, but small changes go a long way. Regular dental visits, consistent brushing and flossing, and smart eating choices prevent most dental disease.
