Toothache under crown, 13 remedies to ease tooth pain.

Best Home Remedy for Toothache Under Crown – 13 Ideas

The pain from an infection under a crown is unbearable. There are many causes – most starting with bacteria – but let’s skip the cause (your dentist will determine this when you see them) and skip right to some quick and effective solutions you can do at home!

Here’s our list of the best home remedies to help ease your pain!

LEDs: Blue Light and Red Light Therapy

Over 3000 clinical studies show how LED blue and red lights at the right wavelength can combat oral bacteria and biofilms.

Blue LED light (400-500 nm range) kills the bacteria that causes many periodontal issues and the resulting pain from these problems. Enterococci can cause abscesses, infections, cavities and tooth decay. And red light in the 600-680 nm range can help to greatly reduce inflammation, pain, bleeding, swelling, and soreness.

We chose Starlite Smile’s gum lights because they are very affordable and have thousands of reviews testifying to the benefits of red and blue light therapy in aiding with toothaches and pain.

Oil of Oregano

Oil of Oregano has antioxidant as well as antibacterial properties. It has been shown to help with reduction or pain, gum disease, bad tastes, and swollen soft tissues.

Saltwater Rinse

Salt has been used for hundreds (maybe thousands) of years for healing wounds. It draws out bacteria. So don’t disregard this tried-and-true home remedy just because it sounds too easy.

1/2 tsp table salt to 1 cup of warm water. Stir. Spit. Repeat as often as you’d like.

Blend of Essential Oils — Lavendar Oil, Peppermint Oil, Clove and Frankincense Oil

Combine 10 drops each of essential oils, with 2 teaspoons of organic coconut oil. Apply to the tooth and gums (any area with pain, redness or possible tooth decay) for quick relief. You should still make an appointment with your dentist as soon as possible.

Our Pick

Majestic Pure Essential Oils Set

Included Essential Oils: Lavender, Frankincense, Peppermint, Eucalyptus, Lemon, Clove Leaf, Cinnamon Leaf, & Rosemary.

Frankincense, used for many thousands of years to help reduce inflammation, pain, and all sorts of other health issues, has antibacterial properties aiding in cavity prevention and gum disease. Use topically in a oral balm or take in capsules.

Peppermint helps to numb (with menthol) and is antimicrobial. Add to your oral balm or reduce swelling with a moist, chilled peppermint tea bag to the problem area.

Lavender essential oil has Linalool, which is antifungal and antibacterial and can help reduce plaque. It has analgesic effects and is anti-inflammatory.

Clove essential oil contains Eugenol, a molecule with analgesic (pain-relieving), anti-inflammatory, and antibacterial effects. Clove is about 90% eugenol. When applied topically, clove oil’s analgesic qualities make it beneficial for decreasing tooth and gum pain and it may also aid in lowering germs that can lead to cavities because it has antimicrobial effects.

What causes a Tooth Infection under a Crown?

This condition can occur due to several reasons, including:

  1. Tooth decay: Decay can occur in the tooth under the crown, leading to an infection that spreads to the surrounding tissues.
  2. Crown damage: If the crown is damaged or cracked, it can allow bacteria to enter the tooth and cause an infection.
  3. Failed root canal: A failed root canal treatment can leave bacteria behind in the tooth, leading to infection.
  4. Gum disease: Gum disease can cause the gums to recede and expose the base of the tooth, which can lead to infection.
  5. Trauma: Trauma to the tooth can cause the nerve inside to become damaged, leading to infection.

NOTE: It’s important to seek dental care for this issue to best resolve the infection and prevent further spread. We are not dentists and this information is not intended to replace your dentist’s recommendations.

Garlic Paste

Garlic contains a substance called allicin, which is both antibacterial and antimicrobial. This can aid in eliminating oral bacteria linked to toothaches and help with temporary relief from any possible dental infection.

Garlic can be applied to the affected region to speed up healing and lessen pain. It might not do much for your breath, but when you have a toothache, bad breath isn’t very important.

Apply a paste made from a crushed garlic clove to the contaminated area around the abscess.

Ice Compression

Swelling takes place in the area when you have an infection. The blood vessels are constricted when ice is applied to the area, which lessens discomfort and swelling. Although the symptoms will lessen in the gum tissue, this won’t clear up the abscess. So it’s great for temporary relief of gum cysts, until you can get to the dentist.

Use an ice pack (cold compress) on the area of any tooth abscesses for fifteen minutes, on and off, several times during the day.

Aloe Vera

Aloe Vera is frequently described as a miracle plant. It is also high in antioxidants and has anti-inflammatory and antibacterial properties. You can ease your pain and encourage your body’s ability to heal naturally by applying aloe vera to the infected area. It is very calming. It is not a long-term solution for a serious infection such as periodontal abscesses or other dental issues, but can provide great relief while waiting for your appointment.

It may be best to apply an organic aloe vera gel such as Seven Minerals brand (grown here in Southern Texas, NSF Organic, IASC Certified), instead of using straight from a plant, just to avoid any possibility of outside germs causing further issues.

Just rub the gel on the affected area for temporary tooth pain relief.

Oil Pulling — Coconut Oil, Olive Oil, or Both

Coconut oil can be utilized to draw the infection out and aid in the deflation of any sore spot on your gums because it has both antibacterial properties and anti-inflammatory properties. Use coconut oil (or olive oil) by swishing a tiny amount around in your mouth for two minutes. Don’t swallow it! Spit it out as the oil will have absorbed toxins.

You may choose to add other essential oils (as shown above) to your oil pulling mix for added benefits of possible pain relief and reduction of swelling. For additional relief apply more of your mix topically (after oil pulling) by gently massaging the oil or mix into the sore teeth and gums. Or try this coconut oil pulling for teeth kit.


These are nine very effective at-home treatments for toothaches. But remember toothaches may indicate a number of oral health issues, especially if they last for an extended time. Your teeth and gum health is critically important to your overall health as well, so finding the underlying cause of your dental issues involves 1.) see your dentist regularly. 2.) start a good oral hygiene routine for ongoing gum disease prevention.

Act quickly if you suspect a tooth infection, abscess, or bacterial infection. Some infections can be life-threatening and considered a dental emergency.

Daily oil pulling, using LED red and blue light therapy devices 3 to 5 times a week, adding herbal teas, especially fenugreek tea, and natural antibiotics such as the essential oil blend are a great start to good dental care at home. These natural remedies can be preventative (keep you out of the dental emergency room :), as they help combat the dreaded tooth extraction, root canal treatment, dry mouth, bleeding gums, and other dental emergencies that hopefully can be avoided with just a little planning.

An untreated abscess is nothing to ignore so for sure see a dentist to see what’s going on and then continue to use the natural treatments as an ongoing routine.
