Emergency Dentist for Redwood Shores: First Hour Guide

If you have a dental emergency in Redwood Shores, call a dentist right away, protect the tooth or injured area, and expect a focused exam with a targeted X-ray rather than a pile of scans or an automatic antibiotic prescription. The first hour matters most for a knocked-out tooth, while swelling that spreads toward the eye, neck, or airway belongs in an emergency room.

This article is general education, not a diagnosis or individual advice. For trouble breathing or swallowing, uncontrolled bleeding, or a head injury, call 911 or go to the nearest emergency room.

What should you do in the first hour of a dental emergency?

Each problem has a different priority. Here is what dental guidance generally recommends while you arrange care.

Knocked-out adult tooth

• Pick the tooth up by the crown (the chewing surface) and avoid touching the root.
• If it is dirty, rinse it briefly in milk or saline. Plain water is no longer the preferred rinse, and scrubbing can damage the delicate cells on the root.
• If you can, gently place it back into the socket. If not, keep it moist in milk, saline, or tucked between the cheek and gum if the person is alert and old enough not to swallow it.
• Call a dentist immediately. International Association of Dental Traumatology (IADT) guidelines emphasize replanting a tooth as soon as possible, ideally within about 15 minutes, because the root cells become more compromised the longer the tooth stays dry, especially past about an hour. A longer delay does not always mean the tooth is lost, so it is still worth calling.
• Do not replant baby teeth. If the person is dazed or unconscious, seek emergency care first.

Broken or chipped tooth

Rinse your mouth with warm water, hold a cold compress against the cheek or lip near the tooth, and save any fragments you can find. Call the same day, even if the pain is mild.

Lost crown

Keep the crown and bring it with you. If you want temporary relief, a pharmacy dental cement can hold it in place for a short time. Do not use super glue, which can complicate the repair.

Facial swelling or a suspected abscess

A gentle saltwater rinse and a cold compress on the outside of the face can ease discomfort, but they do not treat the cause. Go to an emergency room, or call 911, if swelling is spreading toward the eye or neck, if swallowing or breathing becomes difficult, or if you have a fever along with the swelling.

Why does calling early widen your options?

Time changes what is possible. A knocked-out tooth has a narrow window for replanting. An infected tooth caught early can often be treated with a root canal or drainage before it spreads, while a delayed one may call for more extensive care. Even a cracked tooth gives a dentist more choices when it is evaluated promptly.

A phone call also helps the office plan. Describing what happened, what hurts, and whether you see swelling lets the team decide how soon you need to be seen and what to prepare. Many offices hold time for urgent problems. Many people wonder whether a problem is worth a call. If you are unsure, call.

What should you expect at the office?

Two 2026 updates from the American Dental Association (ADA) shape how emergency visits are handled, and both favor doing only what the situation requires.

Imaging: start simple, stay targeted

The ADA's January 2026 patient-selection recommendations for radiographic exams, described as the first update on this topic in more than a decade, say X-rays should be taken only when clinically needed after a thorough exam. For a toothache or suspected infection, standard two-dimensional X-rays are a common starting point. Cone-beam CT, a 3-D scan, is generally reserved for cases where the flat images do not answer the question, and then with the smallest field of view that provides the needed information. Many emergency visits begin with an exam and one or two focused images, and your dentist will decide whether additional imaging is needed for your situation.

Antibiotics: not a substitute for treatment

The ADA Council on Scientific Affairs' August 2026 statement on antibiotic prescribing reinforces that localized dental infections in otherwise healthy adults are treated by fixing the source: a root canal or pulp therapy, drainage, or extraction. Antibiotics are generally reserved for signs that infection is spreading or affecting the whole body, such as significant swelling or fever. The statement also notes that unneeded antibiotics carry real risks, including gut problems. Whether antibiotics are appropriate depends on your health history and exam findings, such as a weakened immune system or certain heart conditions, so follow your dentist's individual recommendation.

Common questions about dental emergencies

For a toothache, broken tooth, lost crown, or knocked-out tooth, a dentist is usually the right first call. Call 911 or go to an emergency room for swelling that spreads toward the eye or neck, trouble breathing or swallowing, or injuries involving the head or heavy bleeding.

Not automatically. Current guidance favors treating the source of the infection first. Antibiotics are added when there are signs of spreading infection or whole-body illness, and the decision depends on your health history and exam findings.

Often not. Standard 2-D X-rays answer many emergency questions, and a 3-D scan is used when those images are not enough or when your dentist judges it helpful, such as in some trauma cases. Your dentist will decide whether additional imaging is needed for your situation.

Outcomes are generally better with faster replanting, but a dentist can still evaluate the tooth and discuss options. Call rather than assuming it is too late.
