Can Bad Teeth Cause Weight Gain?

If you are gaining weight and don’t know why, then there is a possibility that your oral health could be playing a role in it. It is hard to imagine that bad teeth can cause weight gain, but it is true.

There is a complicated relationship between your overall health and oral health. There are several ways in which bad teeth and poor oral health can contribute to weight gain and inflammation in the body. In this article, we will discuss can bad teeth cause weight gain?

Avoiding Healthy Foods

When your mouth is unhealthy and causing pain, people often change the diet. Healthy foods like vegetables and fresh fruits are sometimes crunchy and hard, so eating such food with an unhealthy mouth becomes difficult.

Some fruits contain acids that can be painful for sensitive gums and sensitive teeth. Additionally, meat can also cause problems because fibers can stick between your teeth and irritate your gums and teeth.

So what you do? You prefer processed foods instead of natural healthy food. Processed foods lack nutrition and contain an excessive amount of sugar, salt, and fats that are not good for your health. These foods are easy to chew and eat, but can cause problems in the long run. Excessive sugar causes tooth decay, and eating such food can easily result in gaining weight. So, yes, we can say bad teeth cause weight gain.

Are You Finding It Hard To Exercise?

If you have an unhealthy mouth, it could be challenging to exercise. Gum disease is a chronic infection, and lots of resources are required to fight off that infection. Just think about the stomach bug or flu and feel how much energy it zaps from you. Even though an unhealthy mouth or gum infection only takes a fraction of that energy, it is still enough to make it hard for you to stick to your regular exercise routine.

Another thing that can rob you of your energy is diabetes. Diabetes results due to weight gain and can worsen gum disease. Diabetes affects the way your body absorbs and metabolizes energy and can make your workout routine hard. According to the Mayo Clinic, by reducing the body’s resistance to infection, diabetes puts your gums at risk. Gum disease appears to be more frequent and severe among people who have diabetes.

Moreover, Temporomandibular Joint Disorders (TMJ) also causes difficulties in your exercise routine. TMJ causes jaw, neck, and spine to get out of alignment. So, it becomes hard to maintain balance. When you are not able to follow your exercise schedule, it becomes difficult to maintain weight, and you end up gaining weight. (Be sure to check out this article on 5 TMJ pain relief exercises)

Inflammation Results in Weight Gain

Inflammation has a complex relationship with diabetes, oral health, and weight gain. If you have periodontal gum disease, your gums are infected which cause chronic inflammation. When your body responds to chronic infection in gums, inflammatory compounds are released into your body. These compounds change the way your body stores fat and use energy. Furthermore, these inflammatory compounds impact how your body uses proteins that help you feel full instead of hungry. Inflammation also results in fatigue and makes exercise routine hard. As a result, people start to gain weight.


Can bad teeth cause weight gain? Yes, bad oral health can cause weight gain. There is a complex relationship between overall health and oral health. Infected gums, diabetes, and TMJ can alter your workout routine and results in weight gain. A healthy mouth leads to a healthy body and vice versa.
