Nearly 2 million Americans visit emergency departments each year for tooth-related problems. Many of these could have avoided the costly ER visit by seeing an emergency dentist instead. The challenge is that most people struggle to tell when dental pain is something that can wait for the next available appointment or something that needs urgent dental care right away.
Read on to learn about specific situations that require immediate dental care, how to protect your teeth and gums while you're waiting for your emergency dental visit, and where to find the best dentist in Hayward for all your dental needs, including emergency visits.
Five Scenarios When You Need to See an Emergency Dentist
Knowing which dental problems require immediate attention helps you act quickly when it matters, when you consider all the complex tissues, nerves, and blood vessels that are associated with each tooth. If you’re struggling to decide if you need urgent care from an emergency dentist or not, the following list can help:
1. Severe Toothache or Tooth Pain That Won't Go Away
A toothache that lingers for more than a day or two is your body's alarm system telling you something is seriously wrong. And if the pain keeps you awake at night or gets worse instead of better, the issue has likely moved beyond the tooth's outer layer and reached the nerve inside.
This type of persistent pain often signals an abscessed tooth, where infection has built up at the root, or a cavity that has eaten its way deep into the tooth's core. If you notice swelling in your gums or face, or if you develop a fever alongside the pain, it could mean that bacteria from the infection may be spreading to surrounding tissues. These are also clear signs you need emergency dental care.
2. Knocked-Out or Broken Tooth
The minutes after losing a tooth are critical because what happens in the first hour after a tooth gets knocked out determines whether a dentist can save it or not. Here’s what to do if you or a loved one has a knocked-out tooth:
- Pick it up by the white crown part you normally see in your mouth, never by the root
- Rinse it gently with milk or saliva if it's dirty, but don't scrub it or remove any tissue fragments that might be attached
- The best option is to slide the tooth back into its socket right away, then gently bite down on a clean cloth to hold it in place, but if that feels too uncomfortable, store the tooth in a small container of milk or tuck it between your cheek and gums to keep it moist
Saliva and milk both contain proteins that help keep the root cells alive. You have roughly 30 to 60 minutes before those cells start dying, so getting to an emergency dentist fast makes all the difference.
Broken teeth need urgent attention too, especially if the crack exposes the pink pulp inside, creates sharp edges that cut your tongue, or extends down below your gum line.
3. Dental Abscess
A dental abscess is an infection that has formed a pocket of pus, and it ranks among the most serious dental emergencies you can face. Symptoms include:
- Painful, swollen bump on your gums that looks red or even white at the tip
- Pus that is draining out of a bump on the gums
- Bad taste in your mouth
- Severe toothache
- Swelling that spreads to your cheek, jaw, or neck
- Difficulty swallowing
- Fever
Left untreated, a tooth abscess can lead to a condition called sepsis, where infection spreads throughout your body and becomes life-threatening. An emergency dentist can drain the abscess to release the built-up pus and prescribe antibiotics to fight the infection. After the immediate crisis passes, you'll need either a root canal to save the tooth or a tooth extraction to remove it completely, depending on how much damage the infection has caused.
4. Uncontrolled Bleeding Due to a Dental Injury
Bleeding from your mouth should slow down and stop within 10 to 15 minutes when you apply firm, steady pressure. If bleeding continues or is heavy enough that you're spitting out large clots, you need emergency care.
This type of uncontrolled bleeding can happen after a tooth extraction when the blood clot that should form in the socket either doesn't develop properly or gets dislodged too soon. It can also result from cuts to your lips, tongue, or cheeks, especially if the injury is deep or jagged.
While you’re on the way to the emergency dentist, use a clean piece of gauze or a small folded towel and press it firmly against the bleeding spot, and keep your head elevated above your heart. Typically, oral surgery is needed to repair an oral injury with uncontrollable bleeding.
5. Lost Filling or Dental Crown
A dental filling or crown that falls out leaves the inner part of your tooth exposed to everything you eat and drink. Sometimes this causes sharp, shooting pain when anything hot, cold, or sweet touches the area. Other times, you might feel a rough edge that keeps catching your tongue or cheek, or you might notice a dark spot of decay that was hiding underneath the restoration. Many times, this can wait for the next available appointment; however, these situations are dental emergencies when:
- Pain or tooth sensitivity is severe
- You can see obvious tooth decay
- The tooth is damage is exposed
- Sharp edges are cutting the inside of your mouth
