A cavity
Decay that has reached beyond the surface. It often shows up as a twinge with sweets, cold or heat before it becomes a steady ache.
Toothache, Boise
A toothache can come from a cavity, a crack, a lost filling, a gum problem or an infection, and they can feel alike. Only an exam tells which one you have. Call before 3:30 pm on a weekday and we hold a same-day slot.
Possible causes
These are the usual suspects. We do not guess from the phone. The exam decides.
Decay that has reached beyond the surface. It often shows up as a twinge with sweets, cold or heat before it becomes a steady ache.
A crack can hurt only when you release a bite, and it is hard to see. X-rays and a bite test help us find it.
The tooth under an old filling can decay or become sensitive when the seal fails.
Swollen, tender or bleeding gum next to the sore tooth. Food trapped under the gum can cause pain that feels like the tooth itself.
A deep, throbbing ache that wakes you, sometimes with swelling or a bump on the gum. This needs a same-day exam.
Tonight
Only if it is safe for you, and not more than the label allows. Never put aspirin on the gum, because it can burn the tissue.
Fifteen minutes on, fifteen off. Avoid heat on a painful tooth.
Extra pillows help when pain is worse lying flat.
Chew on the other side. Brush gently around the sore tooth and rinse with warm water.
Tell us when it started, what sets it off and whether there is swelling.
A swollen face with a fever is a medical emergency, not a wait-for-the-morning one.
The visit
We start by listening. When did it start, what sets it off, what eases it. Then an exam: looking, tapping, testing with cold and checking your bite. An X-ray shows what the eye cannot, such as decay between teeth or changes at the root.
Then you get a plain answer and options. Treatment might be a filling, a crown, or care for the nerve of the tooth. Root canal treatment may be done here or with a referral to an endodontist, and we tell you which is the better fit. Nothing is done before you see the plan and the estimate in writing.

Pain patterns
This is a guide to what to tell us, not a diagnosis. Two causes can feel the same.
| What you notice | One possible cause | Why an exam matters |
|---|---|---|
| A quick zing with cold that fades | Exposed or worn tooth surface | It may need only a filling or a sensitive-tooth plan |
| Pain that lingers after hot or cold | Decay or irritation near the nerve | Treatment depends on how deep it is |
| Sharp pain when you release a bite | A crack in the tooth | Cracks are hard to see and spread over time |
| Steady throbbing, worse at night | Inflamed nerve or infection | Needs a same-day exam and X-ray |

The pain can ease while the cause stays. A cavity or crack does not heal by itself, and pain that fades can come back worse. If it lasted more than a day, or woke you up, have it looked at.
If there is swelling, a fever or pain at night, do not wait. If it is a mild twinge, call and describe it. We tell you whether today or a regular visit is the right call.
Over-the-counter pain relief taken as the label directs is what most people use, if it is safe for you. Ask a pharmacist if you take other medicines. Never place aspirin on the gum.
Often yes, because a toothache cannot be judged by looking alone. We use the smallest number that answers the question and explain why before taking it.
Not always. Many toothaches are a cavity or a crack that a filling or crown can handle. If the nerve is involved, the dentist explains your options, which may include a referral to an endodontist.
We do not list prices on this site. You get a written estimate after the exam and before treatment. We work with most major PPO plans.
