A broken tooth needs professional repair, but until you can get to a dentist, your job is simple: protect what’s left, manage pain, and avoid making the damage worse. Most broken teeth can wait a day or two for treatment as long as there’s no heavy bleeding, significant swelling, or fever. Here’s exactly what to do in the meantime.
Immediate First Aid Steps
Start by rinsing your mouth gently with warm water to clear away debris and blood. If the area is bleeding, press a piece of clean gauze or a damp tea bag against it with steady pressure for 10 to 15 minutes. A cold compress on the outside of your cheek, 20 minutes on and 20 minutes off, will help with both swelling and pain.
If you can find the broken fragment, store it in a small container of milk. Milk protects the living cells on the tooth surface better than water. Saliva works as a second choice if milk isn’t available. Bring the fragment to your appointment because your dentist may be able to bond it back on, especially if the break is clean. For a tooth that’s been fully knocked out, the general guidance is to get to a dentist within 30 to 60 minutes, though teeth stored properly in milk may still be viable after longer periods.
Covering Sharp Edges
A broken tooth often leaves a sharp edge that cuts into your tongue, cheek, or lip. Dental wax or a temporary filling kit from any pharmacy can solve this. Clean the tooth area gently with warm water first, then dry it with a tissue or cotton swab. Roll a small piece of wax between your fingers to soften it, then press it directly over the sharp edge to create a smooth barrier. If the wax falls off while eating or sleeping, just reapply it.
Never use superglue, household adhesives, or any DIY bonding material. These can damage the tooth further and introduce chemicals into your mouth that make professional repair harder.
Managing Pain and Getting Sleep
Over-the-counter pain relievers are your best tool here. For mild to moderate pain, ibuprofen (400 to 600 mg every six hours) or acetaminophen (325 to 650 mg every six hours) taken on a schedule works better than waiting until the pain flares up. For more intense pain, you can take both ibuprofen and acetaminophen together, since they work through different mechanisms and combining them is more effective than either one alone. Just keep your total acetaminophen under 3,000 mg per day from all sources.
Sleeping can be the hardest part. When you lie flat, blood pools around the injury and creates a throbbing pressure that keeps you awake. Elevating your head about 30 to 45 degrees, roughly two to three pillows, noticeably reduces this. A reclining chair works well too. The goal is an angle that takes pressure off the tooth without straining your neck.
What to Eat and Drink
A broken tooth may expose the inner layers of the tooth, or even the nerve, making it extremely sensitive to temperature and pressure. Keep all food and drinks lukewarm rather than hot or cold. Stick to soft foods: yogurt, scrambled eggs, mashed potatoes, smoothies, soup that’s cooled down. Chew on the opposite side of your mouth from the break.
Avoid hard foods like nuts, chips, and raw vegetables. Sticky foods like caramel, toffee, and gum can pull on the damaged tooth or dislodge temporary wax. Crunchy items like popcorn and granola can wedge into the crack and deepen it. Skip acidic drinks like soda and citrus juice, which irritate exposed tooth layers. Don’t use a straw either, because the suction pulls air across the exposed nerve.
When It Can’t Wait
Most chipped or cracked teeth are not emergencies, but some situations need same-day or emergency care. Watch for these signs of infection or serious damage:
- Fever, which signals the break has led to an infection spreading beyond the tooth
- Swelling in the gum, jaw, cheek, or face that’s getting worse rather than staying stable
- Persistent bad breath or a foul taste in your mouth, which can indicate an abscess forming
- Pain that radiates to the ear, eye, or neck
- A tooth that feels loose in the jaw or is raised higher than the teeth next to it
- Heavy bleeding that doesn’t stop after 15 to 20 minutes of steady pressure
A dental abscess can develop when bacteria enter the tooth through the fracture. The tooth may feel tender, become sensitive to heat and cold, or hurt when you press on it. Abscesses cause swelling and inflammation that can spread to the jaw, cheeks, and the floor of the mouth. An untreated abscess is a serious health risk, not just a dental problem.
What the Dentist Will Do
Treatment depends entirely on how deep the break goes. A small chip that only affects the outer enamel is the simplest fix. Your dentist can smooth it down or use composite bonding, which typically costs $350 to $700 per tooth, to reshape it. The process takes one visit and doesn’t require numbing in many cases.
A deeper break that reaches the sensitive inner layer but doesn’t expose the nerve usually needs a crown. Crowns cap the entire visible portion of the tooth and run $1,200 to $2,500 per tooth. If the fracture exposes the nerve (you’ll likely know because the pain is intense), the dentist will try to preserve the living tissue inside the tooth with conservative treatments. When that’s not possible, a root canal followed by a crown is the standard path.
Teeth that are cracked vertically down toward the root, or broken below the gum line, have fewer options. Your dentist will take X-rays to see how far the damage extends before recommending a plan. Bringing in the broken fragment can sometimes save you from needing a full crown, since it can be bonded back into place if the edges match cleanly.
