My Tooth Tastes Weird – Possible Reasons

So, you have a weird taste in your mouth and you suspect it might be coming from your tooth?

Now, there are a few possible reasons for this and one of the most common causes is an infection caused by releases from an abscess in your mouth, or an infection in your gums or a jawbone. In case the infection is still at it’s early stage, the bad taste most likely won’t be accompanied by pain and because of it, you might notice a weird taste for days, weeks and even months before you start feeling the pain and by the time you do feel it, the infection, unfortunately,  has already spread and the bacteria may already be in your circulatory system, affecting other organs, such as your heart.

The bad taste that you’re experiencing may vary. Some patients describe it as bitter, or sour, while others say it’s merely unpleasant, and the third ones say that it’s changing from time to time. No matter what it tastes like, you should contact your dentist immediately, because the infection might lead to oral decay and it could also be halitosis.

Halitosis, also known as bad breath

Halitosis is a symptom characterized by an unpleasant odor in your breath. It is often associated with anxiety, depression and obsessive-compulsive disorder among those affected by it. In about 85% of halitosis cases, the bad smell comes from the inside of the mouth, while in the rest of the cases the disorder could be in the nose, sinuses, throat or stomach. Rarely, bad breath can happen due to underlying medical conditions, such as a liver failure or ketoacidosis in diabetics.

When it does come from the oral cavity itself, it’s most likely caused by advanced tooth decay and an infection that might be following it. In this case it’s easily treatable with the improvement of oral hygiene as a first step, followed by resolving the existing issue on the tooth at the dentist’s office.

The treatment depends, of course, on the cause of the issue. Initial efforts include brushing teeth more often, tongue cleaning, rinsing your mouth and regular flossing.

Often, halitosis is viewed as a social taboo, and those affected by it are stigmatized, which is one of the most common reasons they seek dental care. It is estimated that rates of bad breath are going up to even 50% of the population in the United States, although not all cases are classified as halitosis.

Poorly maintained, old or just bad tooth fillings

Another common reason that you’re tooth tastes weird is that you have bad or worn out dental fillings, especially if they’re falling apart and causing sort of a metallic taste. Even if you have fillings made out of more durable materials, they could still erode during time. If that happens, bacteria can now freely inhibit the tooth, causing a bad odor and taste in your mouth.

If this problem is left untreated, it can cause tooth decay and even result in tooth extraction. If the poorly maintained filling is the reason of this weird taste, it should be replaced with another one as soon as possible because the more you wait, the more bacteria accumulates, increasing the chance that the dentist won’t be able to save your tooth, leaving him the extraction or at least a root canal therapy as the only options, which is really unnecessary.

Other possible reasons for the weird taste

Poor oral hygiene. In case you’re not brushing your teeth and flossing regularly, the development of the gingivitis is inevitable, as well as a possible tooth infection. Your dentist might recommend a prescription medicine, such as antibiotics, to get rid of the infection first, and once that’s been taken care of the weird taste should disappear. But what’s more important than that is that you take the matter into your own hands, literally. Brushing your teeth at least two times a day, followed by flossing, as well as rinsing your mouth, is a necessity if you want to keep your oral cavity healthy.

Prescription drugs. Antibiotics, gout medicine and cardiac drugs are some of the medications that can affect your taste and your taste buds as well. Apart from these prescription drugs, some over the counter vitamins are also known for the taste change that they cause. Vitamin and mineral supplements, such as copper, zinc and other heavy metals can cause a metallic taste in your mouth, which shouldn’t last long after you stop using them.

Inadequate diet. A giant factor to your mouth tasting weird is also your choice of food and drinks. Food rich in simple carbs and especially sugars are known to cause a bad taste afterwards, as well as sugary drinks, that are also very acidic and can cause bad reactions in your stomach, causing a whole lot of aftermath. Besides that, they can and will wear out the outer, protective, layer of your teeth, also known as enamel, leaving the tooth more prone to damaging. They are also a lead cause of tooth decay, especially in children, which is a reason good enough to cut their consumption a lot, or eliminate them completely from your diet, which will also affect your overall health and wellbeing. Common and often consumption of alcoholic beverages, especially hard liquors, such as vodka and whiskey, is proven to leave you with a bad taste in your mouth after a certain amount of time.


Inadequate diet and improper hygiene are truly the only factors you can take care of by yourself, by practicing self-discipline, and get rid of that bad taste. In all other cases, dental assistance is most definitely needed in order to fix the original problem that’s causing the weird taste and bad breath, so make sure to schedule your dentist appointment as soon as you start feeling the symptoms, if nothing else, just to get a regular teeth cleaning which will keep your mouth healthy and less prone to problems like this.
