Do you ever catch yourself chewing on a pen cap or clenching your jaw during a stressful meeting? You’re not alone. Many folks in Brandon do things with their teeth and jaw that they don’t even notice. These are called parafunctional habits, and they can cause serious harm to your smile over time.
At Dental Theory, we see the effects of these habits every day. Cracked teeth, sore jaws, and worn-down enamel are just a few signs. The good news? Once you know what to look for, you can protect your teeth before real damage happens. Let’s walk through 15 common parafunctional habits and what you can do about each one.
What Does Parafunctional Mean in Dentistry
Parafunctional habits are actions your mouth does outside of its normal jobs, like eating and talking. Your teeth and jaw were built for chewing food and speaking clearly. When you use them for other things, like grinding or biting objects, that’s called parafunction.
These habits often happen without you even realizing it. Stress, anxiety, and even boredom can trigger them. Over time, they wear down enamel, crack teeth, and strain your jaw joint.
15 Examples of Parafunctional Habits
Here’s a full list of the most common parafunctional habits we see at our Brandon dental office. Some might surprise you.
1. Teeth Grinding (Bruxism)
Bruxism is one of the most common and damaging parafunctional habits. Many people grind their teeth at night without knowing it. This can wear down enamel and cause jaw pain. Learn more about how bruxism affects your sleep and your smile.
2. Jaw Clenching
Clenching happens when you press your teeth together tightly, often during stress. It puts pressure on your jaw joint and can lead to headaches.
3. Nail Biting
Biting your nails puts unnatural pressure on your front teeth. It can also chip enamel and push teeth out of alignment over time.
4. Chewing on Pens or Pencils
This habit seems harmless, but it can crack teeth or damage fillings. Hard plastic isn’t meant for your bite.
5. Ice Chewing
Crunching on ice cubes feels refreshing, but ice is surprisingly hard on your enamel. It’s a leading cause of chipped and cracked teeth.
6. Chewing on Fingernails or Cuticles
Similar to nail biting, chewing on cuticles adds stress to your front teeth and can introduce bacteria into small cuts.
7. Using Teeth as Tools
Opening bottles, tearing tags, or ripping packaging with your teeth puts them at risk of cracking or breaking.
8. Thumb or Finger Sucking Beyond Childhood
This is common in young kids, but if it continues too long, it can affect jaw growth and tooth alignment. Dr. Pri often talks with parents about this during checkups. Learn more about choosing the right dentist for your child’s needs.
9. Lip or Cheek Biting
Chronic lip or cheek biting can cause sores and, in some cases, contributes to jaw tension and bite issues.
10. Tongue Thrusting
This happens when the tongue pushes against the teeth too often, sometimes during swallowing or speaking. It can shift teeth over time.
11. Chewing Gum Excessively
While gum itself isn’t harmful, chewing for hours each day overworks your jaw muscles and joint.
12. Grinding During Concentration
Some people grind their teeth without stress, just while focusing on a task like driving or working. It’s still damaging, even without anxiety involved.
13. Holding Objects with Teeth
Whether it’s holding a phone, a hairpin, or tools, this habit puts uneven pressure on specific teeth.
14. Biting Pens, Straws, or Toothpicks
Biting down repeatedly on small objects can loosen fillings or crack enamel over time, especially with molars.
15. Bruxism Combined with TMJ Disorder
When grinding pairs with jaw joint issues, you may notice popping sounds, pain when chewing, or difficulty opening your mouth wide.
Common Signs You Might Have a Parafunctional Habit
Not sure if you’re dealing with one of these habits? Watch for these warning signs.
- Morning headaches or sore jaw muscles
- Teeth that feel sensitive to hot or cold
- Visible wear, flattening, or chips on your teeth
- Jaw popping or clicking when you chew
- Cracked fillings or crowns without an obvious cause
- Waking up with a tight or tired feeling in your jaw
Why These Habits Matter for Your Dental Health
Parafunctional habits don’t just wear down your teeth. They can lead to bigger problems if left untreated. Here’s what can happen over time.
- Enamel erosion that leaves teeth weak and sensitive
- Cracked or broken teeth that need crowns or repair
- Jaw joint disorders like TMJ dysfunction
- Gum recession from excess pressure on teeth
- Chronic headaches and facial pain
If you’re already dealing with a cracked or damaged tooth, general dentistry care can help repair the damage before it gets worse.

Protecting Your Family From Parafunctional Habits

She works closely with families to catch these issues before they affect permanent teeth. If your child grinds their teeth at night or bites their nails constantly, it’s worth mentioning at their next visit. Explore our pediatric dental services to learn how we support growing smiles.
When to See a Dentist About These Habits

- You notice new sensitivity in one or more teeth
- Your jaw feels sore when you wake up
- A filling or crown has cracked more than once
- Someone has mentioned hearing you grind your teeth at night
- You catch yourself clenching during the day
