Even though a root canal removes the infected pulp from inside your tooth, some people continue to feel pain afterward. This can happen for a few reasons, there might still be some bacteria left behind, the surrounding tissues could be inflamed, or your bite may be slightly off. Let’s go through the common reasons why your tooth might still hurt after a root canal and what you can do about it.
How to Stop Throbbing Pain After a Root Canal: Remedies and Management
1. Medications
After a root canal, throbbing pain or discomfort is normal and can be managed with medications:
- Over the counter pain relievers: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or acetaminophen, also known as paracetamol, help reduce both inflammation and pain.
- Combination therapy: Using NSAIDs along with acetaminophen may provide better pain relief than using either medicine alone.
- Prescription medications: If your pain is more intense, your dentist may prescribe stronger painkillers or corticosteroids to reduce swelling and discomfort.
Make sure to take your medications exactly as prescribed, usually up to four times a day, until the pain goes away. Always follow your dentist’s advice for the best results.
2. Home Care and Comfort Measures
Ice packs: During the first 24 hours after your root canal, gently apply an ice pack to the outside of your cheek (near the treated area) for 15 minutes at a time. This helps reduce swelling and numb the pain.
Warm compress: After 24 to 48 hours, switch to a warm compress. This can relax muscles, improve blood flow, and ease ongoing pain.
Sleep with your head elevated: Use an extra pillow to keep your head slightly elevated while sleeping. This can lower blood pressure in the affected area and reduce throbbing pain at night.
Avoid chewing on the treated side: Especially in the first few days, avoid chewing hard or crunchy foods on the side of your mouth that has the root canal. This prevents further irritation.
Saltwater rinses: Gently rinse your mouth with warm saltwater (mix half a teaspoon of salt in a cup of warm water). This keeps the area clean and soothes the gums.
Clove oil: For temporary relief, you can apply a small amount of clove oil to the sore tooth using a cotton swab. Clove oil contains eugenol, which has natural numbing and antiseptic properties.
Eat Soft Foods and Stay Hydrated
For the first few days after your treatment, it’s best to eat soft foods that aren’t spicy or too hot. This helps prevent any extra pain or irritation. Also, make sure you drink plenty of water. Staying hydrated keeps your mouth clean and helps with the healing process.
Brush Gently
You should keep brushing your teeth, but be extra gentle around the area that was treated. Use a soft-bristled toothbrush to avoid hurting your gums or bothering the tooth that had the procedure.
3. Dental Follow-Up and Further Treatment
If you’re experiencing:
- Severe pain
- Persistent throbbing a week after the root canal
- Or your tooth still hurts after the procedure
You should visit your dentist immediately. This could indicate complications such as:
Incomplete cleaning: Sometimes the canals are not fully disinfected and may require retreatment.
Infection: If an infection is present, your dentist may prescribe antibiotics.
Bite problems: If the dental crown or filling is too high, it may cause occlusal trauma, leading to pain when biting.
Occlusal adjustment: Your dentist may perform a minor adjustment to relieve pressure on the treated tooth.
