Key takeaways
- A knocked-out tooth, bleeding that won’t stop, facial swelling, jaw trauma, unbearable pain, or an abscess means today — not next week.
- Small chips, brief sensitivity, a dull ache, and a lost filling with no pain can usually wait a day or two.
- Swelling and fever move anything up the list, no matter how mild the pain feels.
- Not sure? Call 210-807-7205. Talking it through over the phone costs nothing.
Most people typing “is this a dental emergency” into their phone are not panicking. They are standing in the bathroom at 9pm, poking at a tooth, trying to work out whether to rearrange tomorrow. That is a reasonable question, and it has a reasonable answer.
Dental problems sort into two piles more cleanly than you might expect. Here is how to tell which one you are holding.
Call today: the true emergencies
A knocked-out permanent tooth. This is the most time-sensitive problem in dentistry. Your best chance of saving it is in the first 30 to 60 minutes. Pick it up by the crown, never the root, rinse it gently if it is dirty, and either slip it back into the socket or drop it in a cup of milk. Then drive.
Bleeding that will not stop. Some bleeding after an injury or an extraction is normal. Bleeding that continues after 15 minutes of firm, uninterrupted pressure with clean gauze is not.
Swelling in the face, cheek, or jaw. Swelling means infection has moved beyond the tooth. It can escalate faster than people expect. If swelling starts to affect your breathing or swallowing, spreads under your tongue or down your neck, or comes with a high fever, go to an emergency room or call 911 — that is past what any dental office can handle.
A blow to the jaw. Warning signs include a bite that suddenly does not line up, difficulty opening or closing fully, or numbness in the lip or chin. Any loss of consciousness, vomiting, or confusion after a head injury goes to the ER first.
Pain you cannot control. If over-the-counter painkillers are no longer touching it, or the pain is keeping you awake, the nerve is likely involved. Waiting will not fix that.
An abscess. A pimple-like bump on the gum, a bad or salty taste, throbbing that comes and goes. The dangerous part is that draining relieves the pressure, so the pain fades while the infection quietly keeps destroying bone. Painless does not mean resolved.
Usually fine to wait a day or two
- A small chip with no pain, no sharp edge cutting your tongue, and no exposed pink or bleeding point
- Mild sensitivity to cold that stops within a second or two of the trigger going away
- A dull ache that comes and goes and responds to ibuprofen
- A lost filling or crown where the tooth underneath is comfortable
One caveat: “wait” here means a few days, not a few months. These are problems that will get more expensive if ignored, just not tonight.
What to do in the meantime
If it is urgent: call before you leave so a room and an X-ray are ready. Cold compress on the outside of the face, never heat, which encourages swelling to spread. Sleep propped up on two or three pillows if the pain spikes when you lie flat. Do not put aspirin directly on the gum.
If it can wait: rinse with warm salt water after meals, chew on the other side, cover a sharp edge with dental wax or sugar-free gum, and use pharmacy temporary filling material rather than any household glue. Book something for the next few days rather than hoping it settles.
When you genuinely cannot tell
That gray zone is real, and it is exactly what the phone is for. Tarsem Lal, DDS, has spent years triaging these calls, and the pattern is consistent: the details that decide urgency are rarely the ones patients think matter. How long the pain lingers after cold, whether swelling has changed since morning, whether the ache wakes you up — those separate “come now” from “come Thursday” far better than how loudly a tooth is complaining.
He tells people to wait when waiting is genuinely fine. A patient who cracks a molar during a lunch meeting downtown does not always need to abandon the afternoon, and being told that plainly is worth the call on its own.

Frequently asked questions
Is a toothache always a dental emergency? No. A dull ache that responds to ibuprofen can usually wait a couple of days. Pain that lingers after hot or cold, wakes you at night, or stops responding to painkillers should be seen today.
My tooth hurt badly for days and then suddenly stopped. Is that good news? Usually not. Pain that disappears abruptly after being severe often means the nerve has died rather than healed. The infection continues without the warning signal. Have it checked.
Should I go to the ER or an emergency dentist? An ER can prescribe antibiotics and pain relief and rule out anything life-threatening, but most do not have a dentist or dental X-ray on site, so the tooth itself goes untreated. Go to the ER first for difficulty breathing or swallowing, uncontrolled bleeding, or a suspected jaw fracture. Otherwise call us first.
Can a chipped tooth wait until Monday? Usually yes, if there is no pain, no sharp edge cutting your tongue, and no pink or bleeding spot visible on the broken surface. If the tooth is sensitive to air or cold, it should be seen sooner.
What if I have no insurance? Call and ask what the visit will cost before you come in. We offer financing and payment plans, and cost should not be the reason a spreading infection goes untreated.
Do you take walk-ins? Yes, though calling ahead means we can have a chair and an X-ray ready and usually gets you seen faster.
