The right treatment depends on a dental examination. These answers explain common choices and questions to ask; they do not identify the cause of your symptoms.
What is the best treatment for a cavity?
Early mineral loss without a hole may respond to fluoride and prevention. A cavity with a hole usually needs a filling; more extensive damage may need other treatment. A dentist checks its depth and whether the tooth can be restored. Treatment should match the problem, rather than automatically choosing the most expensive option.
Why do my gums bleed, and do I need a deep cleaning?
Bleeding can be a sign of gum inflammation. Gingivitis may improve with effective daily cleaning and professional care. Periodontitis involves damage to the tissues supporting teeth and may need scaling and root planing or further treatment. An examination and gum measurements help distinguish them.
Do antibiotics cure a toothache or dental abscess?
Antibiotics do not repair decay or remove an infected tooth’s damaged tissue. For many dental pain and swelling problems, dental treatment is the priority. Fever, feeling unwell or spreading infection can change the need for antibiotics. Contact a dentist promptly; do not use leftover antibiotics.
Should I choose a root canal or have the tooth removed?
A root canal can preserve a tooth with inflamed or infected pulp if it can be restored. Extraction may be appropriate when the tooth cannot be saved. Ask about the crack or decay, gum and bone support, the final restoration and replacement choices if it is removed. An endodontist’s opinion may help when the choice is unclear.
What should I do if a permanent tooth is knocked out?
Seek a dentist immediately. Handle the tooth by its crown, not the root, and keep it moist; milk is an option if it cannot be safely kept in its socket. Do not scrub the root. Time matters. A baby tooth should not be put back in the socket.

When is dental swelling an emergency?
Seek emergency medical care now for trouble breathing or swallowing, or severe spreading swelling. In the United States, call 911 when you need emergency help. Suspected dental abscesses need urgent dental assessment even if the pain temporarily improves.
What helps sensitive teeth?
Sensitivity can come from exposed roots, worn enamel, decay, a crack or other causes. Desensitizing toothpaste or fluoride may help some cases; a damaged tooth may need different treatment. Persistent, worsening or one-tooth pain should be checked rather than covered up with whitening products.
Are dental implants always the best replacement for missing teeth?
No. Implants, bridges and removable dentures have different benefits, costs and maintenance needs. Implant suitability depends on oral and general health, bone, healing and other factors. Complications and implant failure are possible. Ask for an individual comparison and a written plan.
What can I do about a dry mouth?
Ask a dentist or clinician to look for the cause, including possible medicine effects. Do not stop prescribed medicines on your own. Water, saliva substitutes and sugar-free gum may help when appropriate. Dry mouth increases decay risk, so a tailored prevention plan matters.
Is jaw clicking or jaw pain treated with surgery?
Painless clicking alone often needs no treatment. Jaw pain or limited opening should be assessed. TMD care commonly starts with conservative, reversible measures. Discuss the evidence and alternatives before treatments that permanently change your teeth, bite or jaw.
Can a dentist stop decay without drilling?
Some early lesions can be managed without a filling. Silver diamine fluoride can also arrest selected decay under professional supervision; in the US this is an off-label use of a product cleared for sensitivity. It permanently blackens the treated decay and needs follow-up. It is not suitable for every tooth or infection.
Will whitening work on crowns, veneers or fillings?
Whitening products change the shade of natural teeth, not existing crowns, veneers or fillings. That can leave a color mismatch. Sensitivity can occur. Have the cause of discoloration and the health of your teeth checked before choosing treatment.
When should a child first see a dentist?
Arrange the first visit when the first tooth appears and no later than the first birthday. A dentist can check development, discuss brushing and fluoride, and help plan prevention. Later visit intervals should reflect the child’s needs and risk.
Can new research regrow my missing adult tooth today?
The research discussed here does not establish a routine replacement for implants, bridges or dentures. Tooth-regeneration drugs, enamel repair materials and salivary-gland approaches are at different evidence stages. Read the study population and limitations before assuming a result applies to you.
