Toothaches can be a real pain. With CBD (cannabidiol) recently getting attention due to its many applications, you’re likely wondering if CBD oil can help relieve toothache.
There’s no doubt that CBD has become a buzz-word in recent times. If you live in the United States, you may have noticed many hemp products being sold on every corner. From CBD facials to CBD lattes, we’re really getting the best of it.
As popular as it may be, CBD can be somewhat confusing – especially if you’re looking to treat something specific like a toothache. It can be hard to figure out if you should be trying out this product or if it will even work.
CBD has been used for its therapeutic and medicinal purposes for thousands of years.  The most commonly cited reason for using CBD, and other cannabis products, is chronic pain. But what is CBD and can it really soothe toothache?
Today, we’ll be taking a deep dive into CBD and its therapeutic properties. We’ll present how CBD works, and cite scholarly articles that support our statements.
What is CBD?
CBD (cannabidiol) is a compound that originates from the cannabis plant, aka marijuana. There are over 113 known chemicals found in cannabis which are known as cannabinoids. The most popular of these cannabinoids is THC which is what makes you feel high if you smoke marijuana. CBD, which is also obtained from hemp, contains very little THC. (source)
CBD is typically used for epilepsy, anxiety, pain, Parkinson’s disease, and other conditions but there is little scientific evidence to support these uses.
Is CBD Legal?
In 2018 the Farm Bill was passed which made hemp products with <0.3%> of THC legal at a federal level. This effectively made CBD legal federally. CBD products simply have to go through a third-party lab test to ensure that the THC content is within the federal limit of 0.3%.
How Does CBD Work?
CBD works in many ways. Primarily, it interacts with your own endocannabinoid system. According to Harvard Health CBD may help with those in need of managing anxiety, insomnia, and even chronic pain.
Although more studies need to be done to measure the effectiveness of CBD, you can see why many have turned to CBD when experiencing pain and even tooth pain.
According to the same Harvard study listed above, CBD seems to prevent the breakdown of brain chemicals that affect pain and mood. By preventing the breakdown of these chemicals CBD seems to reduce the effects of pain and anxiety.
What Causes Toothache?
A toothache can be caused by many reasons some of the most common are the build-up of bacteria, infection, wisdom teeth, and other factors. When bacteria build up on your teeth they spread in between your gum and teeth causing pain. Poor hygiene can lead to more bacteria.
It’s best to visit a dentist to properly assess your situation and find the source of the pain, especially if the pain has lasted multiple days or even weeks. Also, be sure you have regular teeth cleaning to avoid the build-up of bacteria.
Can CBD Really Soothe Tooth Pain?
CBD has been shown in clinical trials to help in the management of difficult to treat pain. 
Although, according to the U.S. National Library of Medicine there is insufficient evidence to show that CBD is effective in treating anything other than epilepsy. This may be due to the fact that Marijuana (and hemp) was considered to be a schedule 1 substance. This made it extremely hard to conduct clinical trials with Hemp and Marijuana.
How to Use CBD for Toothaches
Although there are no scientific studies showing (that we found) related to CBD relieving toothaches there are multiple studies supporting the idea that CBD can help soothe general or chronic pain.
With that in mind here are a few ways you can use CBD to try and help soothe toothaches.
CBD Oil and Tinctures
CBD Oil Tincture is one of the most popular ways to take CBD. You simply place the oil under your tongue for 60 to 90 seconds and wait for it to dissolve. One of the benefits of taking CBD oil is that you can feel the effects relatively fast (15 to 20 minutes) compared to taking CBD capsules. The effect of taking CBD Oil through the sublingual mucosa (under your tongue) lasts four to six hours.
You can try to place CBD oil on your finger and place it around the affected area. Sometimes it’s best not to touch the affected area so keep that in mind.
CBD-infused toothpaste is another way of taking CBD for toothaches. It’s impossible to say if it will actually help with your toothache but it may be worth a shot. Simply take your toothpaste of choice and add a few drops of CBD oil.
CBD tea can also be another way to take CBD. Simply drop a few Milliliters of CBD into your favorite tea. The tea may also help soothe the toothache with excess heat. Topicals are also of great help (externally). You can rub the affected area with CBD pain cream to see if it helps.
Potential Side Effects
CBD can lead to a dry mouth. Having a dry mouth is a good place for bacteria to grow and can lead to further infection. Be sure you drink plenty of water. Also, try to use mouthwash regularly to kill any bacteria in your mouth, and of course, be sure to floss regularly. As always practice good oral habits to avoid exacerbating the toothache.
Does CBD Make You High?
CBD is only legal when it contains <0.3% >THC. THC is a cannabinoid that has psychoactive properties. If you want to be sure you don’t get high using CBD with THC make sure to get the one containing less than <.3%>. You can also try broad-spectrum CBD oil or a CBD isolate tincture. Both of these CBD products will have 0.0% THC.
Full-spectrum CBD will have the <0.3%> THC so depending on your tolerance level and how much you ingest Full spectrum CBD may get you high, but it’s unlikely.
Should You Use CBD?
Using CBD is completely up to you. It may or may not work depending on your specific situation.
Consult with a Doctor
As always be sure you speak with a medical professional to try and find the root cause of the toothache and properly treat it. Also, try to find out if there is anything you can do to prevent a toothache from happening again in the future.
If you are taking other medications you will need to speak to a doctor as CBD can affect the way those medications interact with your body.
