Dental answers, made clearer
Clear, concise answers to common dental questions—written for people who want the essential information first.
Not always. Some cracks only cause pain when chewing or when exposed to hot and cold, while others, especially hairline cracks, can be painless until they worsen. This is why a cracked tooth that "doesn't hurt" can still need treatment before it splits further.
Read the answerSituations like a knocked-out tooth, uncontrolled bleeding, a severe toothache, facial swelling, or a broken tooth with exposed nerve are generally treated as dental emergencies requiring same-day care. Most clinics, including those offering emergency dental treatment, prioritize these cases over routine appointments.
Read the answerTooth sensitivity usually happens when the protective enamel has worn thin or gums have receded, exposing the dentin layer underneath, which contains tiny nerve endings. Common triggers include enamel erosion, gum recession, teeth grinding, and recent dental work.
Read the answerIt can be, but sensitivity alone doesn't confirm a cavity, since it's also caused by enamel wear, gum recession, or a cracked tooth. If sensitivity is localized to one tooth or getting worse, it's worth having a dentist check for decay underneath.
Read the answerYes, mild sensitivity often improves with desensitizing toothpaste and fluoride treatment, which help block the nerve pathways in exposed dentin. More persistent sensitivity may need a dental sealant, bonding, or treatment of the underlying cause, such as gum recession.
Read the answerWisdom teeth are usually recommended for removal when they're impacted, growing at an angle, causing crowding, or repeatedly trapping food and bacteria. Not every wisdom tooth needs to come out; some erupt normally and cause no problems at all.
Read the answerAn impacted wisdom tooth often causes dull jaw pain, swelling near the back of the mouth, and discomfort when opening wide or chewing. Some people also notice a bad taste or mild fever if the area has become infected.
Read the answerA root canal treatment removes infected or inflamed tissue from inside a tooth's nerve chamber, then cleans and seals the space to stop the infection from spreading. It's typically needed when decay or a crack has reached the tooth's inner pulp, and it's aimed at saving the natural tooth rather than extracting it.
Read the answerA dental crown is a custom-made cap that covers a damaged or weakened tooth to restore its shape, strength, and appearance. Crowns are commonly used after a root canal, on a heavily decayed tooth, or to protect a tooth that has cracked.
Read the answerDental veneers are thin, custom-made shells bonded to the front surface of a tooth to improve its color, shape, or alignment. They're primarily a cosmetic treatment, most often used for discoloration, chips, or minor gaps that don't require full orthodontic correction.
Read the answerFluoride treatment strengthens tooth enamel and helps it resist acid attacks from plaque bacteria, which can slow down or even reverse the very earliest stages of decay. It's commonly applied during routine checkups, particularly for children and anyone at higher risk of cavities.
Read the answerTeeth grinding is commonly linked to stress, an misaligned bite, or sleep disorders, and it often happens unconsciously during sleep. Over time, it can wear down enamel, cause jaw pain, and even lead to cracked teeth if left unmanaged.
