Do you chew your food only on one side?

Weird and bizarre man is eating fat and juicy hamburger. It is not a healthy food but the guy likes it very much. His face is very emotional. Isolated on white background.

Most of us have a dominant or preferred side of chewing. Unlike being left or right-handed which is usually decided by genetics, chewing is decided subconsciously. But if you chew only on one side you might actually be damaging your teeth and your jaw joint.

Various factors like pain, decay, broken teeth, jaw growth, and muscle movement decide which side we chew. So if any of your teeth is hurting on one side you will subconsciously chew from the other side. Similarly, if one side of your jaw is longer than the other, the chances of you eating from that side become very high.

What happens when you chew from only one side?

Attrition of teeth on the chewing side

When you chew only on one side, teeth on that side starts to grind down because of constant friction that happens every time you chew. since your chew only on that side the process is just faster and more aggressive on that side. The other side isn’t spared but instead starts to have a lot of plaque and calculus deposits. We also tend to brush our chewing side better leaving the opposite side with poorer hygiene leading to dental problems.

Sensitivity on the chewing side

Attrided teeth on the chewing side have exposed dentin layers which make it more susceptible to teeth sensitivity.

Tense facial muscles

Same with the muscles of mastication. The used side gets stronger and toned. The less-used side starts to deteriorate and looks slack.  This is why we have a good side and a bad side for taking photographs. But the opposite happens to your jaw.

Pain in the jaw joint

The jaw joint or the Temporomandibular joint that is just in front of your ear supports and guides the mandible or your lower jaw while chewing. It is the delicate focal point of all your bone, tendons, and muscles. Whenever you chew from one side, the other side of the TMJ bears the stress.

This causes a lot of problems in the long run like facial asymmetry, jaw pain, lockjaw, and loss of facial functional balance. 

Chew from both sides

If you cannot chew from both sides visit the dentist to find out the cause of your pain. Fix any broken or decayed teeth to restore your chewing.

If you cannot chew properly due to missing teeth get new teeth fixed. A lot of options like dentures, bridges, implants are available.

Avoid putting unnecessary pressure on your jaw by chewing on pens, pencils, your nails, etc. Don’t sit for long with a propped chin to avoid TMJ damage.

Do you feel pain or clicking noise in your jaw joint?

If you already have jaw damage the first thing you will notice is facial asymmetry. Correction can be done by changing your bite pattern or with braces or Botox injections to reduce the activity of the muscles. In some cases, jaw reshaping surgery might also be required. 

Like we always say prevention is the best cure. So make sure you chew from both the side. Brush your teeth regularly to maintain good hygiene.

Be true to your teeth and they will not be false to you.


  • Chewing only from one side can actually have damaging effects on your teeth as well as jaw joint.
  • Chewing from one side can cause your teeth to wear off and subsequently lead to teeth sensitivity.
  • It can also hamper your facial appearance by making your cheeks sink in and droop down.
  • It can also make your lips on the chewing side droop down due to reduced teeth height.
  • Chewing one one side can damage your TMJ/ jaw joint and cause pain and clicking noise while opening and closing your mouth.
