Cavities, no one can stand them. That sharp, stinging pain in your mouth when trying to enjoy a nice meal can completely ruin your day. Usually caused by a lapse in oral hygiene, cavities can vary greatly in their level of severity. Most remain asymptomatic initially, but almost always grow excruciatingly painful as the decay worsens. Considering how disruptive a cavity can be, it's reasonable to assume that plenty of people wonder, “Can cavities go away?” The answer is a resounding no; you will almost certainly need some sort of treatment once decay has turned into a cavity.

Understanding What a Cavity Actually Is

Before we get into the realities of cavities healing on their own, it's best to break down what cavities actually are. A cavity occurs when tooth decay caused by bacterial acid erosion breaks past the initial layers of enamel, creating a hole. Cavities develop in severity over the course of various stages. Typically starting as white spots on your teeth and eventually moving towards your dentin and pulp as the decay worsens.

The Myth: Natural Remedies Can Heal Cavities

Many online resources make exaggerated claims about natural cavity removal. The truth is, natural remedies are mostly ineffective at treating mild dental issues, let alone a full-blown cavity. Methods such as oil pulling have extremely limited evidence to back up their “cavity-reversing properties,” and most other remedies are purely preventative. Here is a brief breakdown of some of the most common myths surrounding cavity removal:

Myth Fact
You can reverse cavities with coconut oil or oil pulling. Oil pulling can reduce bacteria in some cases, but it cannot repair your enamel or reverse a cavity.
Vitamin D reverses tooth decay. Vitamin D can strengthen enamel, but it won't help you recover enamel that's already been eroded.
Brushing harder removes cavities. Brushing aggressively can actually increase the odds of a cavity developing by damaging your enamel, and no, it can't reverse a cavity.
Cavities go away on their own. You can only reverse the earliest stages of a cavity, before an actual hole has even formed.
If the pain stops, the cavity is gone. The pain may have stopped because your nerve has died, but the decay itself has not stopped.

When your oral health is at stake, you can't rely on wellness blog shortcuts; verifiable science is the only way to go. The very nature of a cavity eliminates the possibility of one going away without professional intervention. Let's break down why.

Why Cavities Usually Don't Go Away

Once the outer layers of enamel have been breached, the damage has been done. Preventative measures such as remineralization can be effective in the earliest stages of tooth decay, but can't do much once a proper cavity has formed. An untreated cavity will only worsen over time, eroding your tooth down to the pulp and eventually causing it to crack and split. They can also cause some deeply unpleasant complications like dental abscesses and infections that can spread through your bloodstream, affecting your organs. Here is a breakdown of how a cavity progresses:

  • Stage 1: Demineralization: Your enamel is stripped of its minerals, which manifests as chalky white spots.
  • Stage 2: Enamel Decay: The surface of your enamel starts to break down, exposing the layers underneath.
  • Stage 3: Dentin Involvement: The decay starts to reach the inner layers of your tooth, causing moderate pain and sensitivity.
  • Stage 4: Pulp Infection: With all of the outer layers breached, bacteria start to infect the tooth's nerve, which can cause excruciating pain.

As you can see, advanced tooth decay cannot be easily resolved with DIY treatment or just waiting for it to pass. If your cavity is past the second stage, you must consult with a dental professional before it becomes unbearable.

Early Stage Reversal

If you’re still in the earliest stages of tooth decay and you’re asking yourself, “How to remove this cavity from my teeth”, you're in luck. The faint white spots caused by demineralization can be stopped or even reversed via a process called remineralization. If you’ve spotted tooth decay in the pre-cavity phase, you should:

  • Use Fluoride: Toothpastes that use fluoride can help restore weakened enamel and bolster it against acidity.
  • Use Calcium & Phosphate: Certain specialized toothpastes contain high concentrations of calcium and phosphate, which can restore the balance of minerals in your teeth.
  • Eat Sugar-Free Chewing Gum: After a particularly acidic or sugary meal, sugar-free gum can stimulate your saliva production and aid your mouth's natural repair systems in restoring slightly damaged enamel.
  • Change Your Diet if Needed: If you’ve been eating irresponsibly and consuming a high amount of sugary foods, those initial white spots on your teeth are your sign to cut it down. Bacteria that cause cavities feed on sugar; you need to cut off their fuel supply.

If your enamel surface has been breached, you're unfortunately out of luck. Remineralization cannot seal that hole. Once an actual cavity has formed, you’ll most likely require a dental filling to prevent further damage.

Proven Methods to Stop & Prevent Cavities

With cavity removal being more of a complex procedure than some wellness blogs would have you believe, there are some genuinely reliable ways to stop new cavities from forming while strengthening your enamel. These methods include:

  • Brushing Twice a Day: It’s generally a good habit to brush your teeth twice a day for your overall oral hygiene. Brushing twice a day with a fluoride toothpaste for at least 2 minutes in gentle circular motions will remineralize your enamel and stop early decay.
  • Daily Flossing: Flossing every day will get rid of any bacteria and debris lodged between your teeth. It's an extremely effective way to remove plaque and prevent cavities before they even start.
  • Eliminate Sugar: As mentioned before, bacteria feed on sugars in your mouth. Steering clear of sugary snacks, sodas, and sticky foods will greatly benefit your oral health. Instead, stay properly hydrated, eat vegetables, and calcium-rich dairy products to neutralize the acids in your mouth.
  • Regular Dental Cleanings: Getting a professional dental cleaning done on occasion can dislodge hardened tartar and catch cavities early. Even if your teeth feel totally fine, remaining proactive with regular checkups stops a mild issue from turning into a severe one.
  • Fluoride Treatments and Sealants: Treatments such as fluoride varnishes or medical-grade dental sealants will give your teeth powerful long-term protection. These treatments are particularly effective for children (who are particularly prone to cavities).

Sticking to these habits will eliminate the question of “how to get rid of a cavity,” as none will form in the first place if you're consistent.

When to See a Dentist

If you think you've got a cavity, waiting for it to magically resolve itself will only make things worse. Sometimes a professional is absolutely necessary; you should schedule an appointment as soon as possible if you notice :

  • Constant dental sensitivity to high or low temperatures and sweetness.
  • Sharp pain while chewing food.
  • Visible holes or dark spots on your teeth.
  • Rough or sharp edges on your enamel.

A dental professional can easily identify and diagnose a cavity by visually examining your teeth or via X-ray. Dentists can catch decay before it even starts to cause discomfort, which usually leads to a much simpler, cheaper, and less intrusive remedy.

The Bottom Line: Cavities Don't Just Go Away

To put it simply, you cannot just wait out a cavity. If the decay has breached your enamel, it isn't going anywhere until a dentist properly treats it. This does not mean that you're helpless when experiencing a cavity; it just means that prevention is your best bet.

You should be completely clear on the difference between early enamel weakness and a full-blown cavity. That clarity allows you to act before the damage cannot be reversed without expensive dental procedures. Keep up with your oral hygiene and don't be lax when it comes to brushing, flossing, or limiting sugary foods. Additionally, see your dentist as often as you can to ensure that decay isn't silently ravaging your teeth.

Cavities won't magically go away, but you don't have to let them get worse either; be proactive about your oral health.

Some dental conditions are quiet. Too quiet, in fact. Odontomas fall into that category. They rarely make noise, yet they change things beneath the surface. And people usually have no idea about them. While malocclusions, teeth shifting, discoloration, or other cosmetic dental issues are fairly well known, odontomas are not. So, an odontoma is technically a type of tooth tumor. It’s benign, harmless, but oddly structured. Hence, it can interfere with tooth eruption, displace teeth, or cause swelling. However, there’s more to it. Here’s a deeper dive.
