Are you waking up with a headache, jaw pain, or chipped teeth after having your wisdom teeth removed? If so, you're not alone. Many people experience the frustrating and uncomfortable habit of grinding their teeth after this common oral surgery. But fear not! In this blog post, we'll dive deep into the causes behind this perplexing phenomenon and provide you with effective solutions to put an end to those sleepless nights and dental woes. So sit back, relax, and let's unravel the mysteries of grinding teeth after wisdom tooth removal together!

Explanation of Wisdom Teeth and Why They Need to be Removed

Wisdom teeth, also known as third molars, are the last set of teeth to emerge in the back corners of a person's mouth. For centuries humans have had these extra sets of molars because our ancestors needed them for their diet rich in rough foods like roots and nuts.  However, with modern advancements and changes in diet habits, our jaws have evolved over time to be smaller than those of our ancestors. This reduction in jaw size has resulted in limited space for these extra molars to grow correctly.  Molars typically appear between the ages of 17-25, and in some cases, they may not even erupt at all. These teeth got their name because they usually come in when a person is older and presumably wiser.

However, these molars often cause problems for many people. Due to lack of space in the mouth, wisdom teeth can become impacted or partially erupted, leading to various issues such as pain and infection. Thus, most dentists recommend removing wisdom teeth before they cause more significant problems.

The Connection Between Wisdom Teeth Removal and Teeth Grinding

Wisdom teeth removal is a common dental procedure that involves the extraction of one or more third molars, located at the back of the mouth. These teeth typically emerge between the ages of 17 and 25, but often do not have enough room to properly grow and can cause issues such as pain, infection, and crowding of other teeth. The removal of wisdom teeth is recommended by dentists to prevent these potential problems.

However, many people who have undergone wisdom teeth removal may experience another issue - grinding their teeth. Teeth grinding, also known as bruxism, is a condition where an individual clenches or grinds their teeth together while sleeping or subconsciously during the day. This can lead to a variety of negative effects on oral health such as jaw pain, headaches, worn-down tooth enamel, and even tooth fractures.

Causes of Teeth Grinding After Wisdom Teeth Removal

After undergoing wisdom teeth removal, it is common for some individuals to experience teeth grinding or clenching. This can be a painful and frustrating issue, as it can cause discomfort and damage to the surrounding teeth. In this section, we will discuss the potential causes of teeth grinding after wisdom teeth removal.

1. Pain and Discomfort: 

The most common cause of teeth grinding after wisdom teeth removal is pain and discomfort in the jaw area. The extraction of wisdom teeth can cause swelling, soreness, and stiffness in the jaw muscles, making it difficult for individuals to find a comfortable resting position for their jaws. As a result, they may unconsciously grind or clench their teeth in an attempt to alleviate the pain.

2. Stress: 

Another factor that can contribute to post-wisdom tooth extraction teeth grinding is stress. The experience of going through surgery can be stressful for many people, leading to increased tension in the jaw muscles which may manifest as grinding or clenching of the teeth.

3. Misaligned Bite: 

Wisdom tooth removal can also result in changes to your bite alignment if there is not enough space for it to grow properly. This misalignment causes changes in how your upper and lower jaws meet when you close your mouth, causing discomfort while biting or chewing food. In some cases, this discomfort may lead to unconscious grinding or clenching of the teeth.  When it comes to grinding your teeth after wisdom tooth removal, having a pre-existing jaw misalignment can make you more prone to this problem. The constant pressure from clenching and grinding your newly extracted molars can exacerbate any existing alignment issues in your bite.

4. Medications: 

Painkillers prescribed after wisdom tooth extraction are often strong medications that have muscle relaxant properties which can lead to grinding of the teeth

Here are Some Solutions that can Help Alleviate Teeth Grinding After Wisdom Teeth Removal:

1. Pain Management:       

The first step in addressing teeth grinding after wisdom teeth removal is managing any pain or discomfort caused by the surgery. Consult with your dentist about taking over-the-counter painkillers or prescription medication if necessary. This will not only help reduce any discomfort but also decrease stress levels that may be contributing to your teeth grinding.

2. Jaw Exercises:

After wisdom teeth removal, your jaw muscles may feel tight and sore which can lead to involuntary clenching and grinding of your teeth. Practicing simple jaw exercises like opening and closing your mouth slowly or gently massaging the area around your jaw joint can help relax the muscles and relieve tension.

3. Identify the Triggers

The first step in finding a solution for grinding teeth after wisdom teeth removal is identifying the triggers that cause you to grind your teeth. Pay attention to when you are most likely to grind your teeth – is it during stressful situations or at night while sleeping? Understanding what triggers your bruxism can help you find ways to manage it effectively.

4. Practice Relaxation Techniques

Stress is one of the main culprits behind grinding teeth after wisdom teeth removal. To reduce stress levels, try practicing relaxation techniques such as deep breathing exercises, yoga, or meditation. These techniques can help calm your mind and body and prevent you from clenching or grinding your teeth.

5. Adjusting Diet and Lifestyle Habits

 Limit Caffeine Intake: Cutting down on caffeine consumption can also have a positive impact on reducing teeth grinding after wisdom teeth removal. Caffeine is a stimulant that can increase anxiety levels and disrupt sleep patterns, both of which are linked to bruxism (teeth grinding). Consider switching to decaffeinated drinks or limiting your intake of caffeinated beverages like coffee, tea, energy drinks, and soda.  

Avoid Alcohol Consumption: Similar to caffeine, alcohol consumption has been linked to increased bruxism activity due to its sedative effects on the central nervous system. It's best to avoid alcohol altogether if you are experiencing problems with grinding your teeth after wisdom teeth removal.  

Eat a Balanced Diet: A balanced diet rich in essential nutrients such as calcium, magnesium, potassium, and vitamin D is crucial for maintaining good dental health and

6. Use a Mouthguard:

A mouthguard is a customized dental device that fits over your upper or lower rows of teeth. It acts as a protective barrier between your upper and lower jaws, preventing them from coming into direct contact with each other while you sleep. Wearing a mouthguard at night can help stop the habit of grinding your teeth at night.

There are two types of mouthguards available - stock mouthguards and custom-made mouthguards. Stock mouthguards are preformed, ready-to-use guards that can be purchased at most drugstores. While they may offer some level of protection, they do not provide a comfortable or secure fit as they are not customized to the individual's mouth.

On the other hand, custom-made mouthguards are made specifically for each patient's unique dental structure. These guards are typically made by a dentist using impressions of your teeth. This ensures a snug fit and maximum protection against teeth grinding.

So how exactly do mouthguards prevent teeth grinding after wisdom teeth removal? The main function of a mouthguard is to act as a shock absorber, distributing the force of grinding or clenching evenly across the entire surface of your teeth instead of concentrating it on specific areas. This helps to reduce the pressure on your jaw joints and minimize any potential damage to your teeth.

In addition to providing cushioning for your jaw, wearing a mouthguard also helps to create separation between your upper and lower jaws. This prevents direct contact between your top and bottom molars, which can result in excessive wear on these teeth.
