Understanding Wisdom Teeth: Why We Have Them and the Reasons for Extraction

Wisdom teeth, also known as third molars, are the last teeth to erupt in your mouth. This usually occurs between the ages of 17 and 25, a phase of life that has been referred to as the “age of wisdom,” hence the name. Let’s delve into the development of wisdom teeth to better understand their function and the reasons for extraction.

The Evolutionary Role of Wisdom Teeth

Human ancestors had a much different diet than we do today. Their food often included raw meat, roots, leaves, and hard fruits, which required a lot of chewing power. The wider jaw of our predecessors could accommodate 32 teeth, including the third molars, to aid in the grinding down of these tough foods.

As humans evolved, our dietary habits changed. The advent of cooking and tools to process food meant less work for our jaws, and over time, our jaws have become smaller. Today, most of us have room for only 28 teeth. As a result, when those third molars try to fit in, problems often arise.

Wisdom Teeth Complications and Extraction Reasons

When there’s not enough room in the mouth for wisdom teeth to grow properly, they can become ‘impacted.’ This means that the teeth are unable to emerge fully from the gums, which can cause a host of complications:

1. Pain and Infection: Impacted wisdom teeth can lead to pain, swelling, and infection in the gum tissues surrounding the teeth.

2. Damage to Adjacent Teeth: The pressure from impacted wisdom teeth can damage neighboring teeth, leading to tooth decay or making these teeth more susceptible to gum disease.

3. Cysts or Tumors: Sometimes, cysts or tumors can form around impacted wisdom teeth, leading to potential jaw damage and requiring further treatments.

Due to these potential complications, dentists often recommend extracting wisdom teeth. This is particularly true in cases where the teeth are impacted, but also in situations where the teeth have partially erupted or grown in at an incorrect angle.

The Extraction Procedure

Wisdom tooth extraction is a common procedure typically performed under local anesthesia, sedation, or general anesthesia, depending on the complexity of the case and patient comfort. During the procedure, the dentist or oral surgeon makes an incision in the gum tissue, removes any bone blocking access to the tooth, extracts the tooth, and then cleans the area and stitches the wound to promote healing. Post-procedure, patients may experience some discomfort, swelling, and bruising, but these symptoms typically subside within a few days.

Wisdom Teeth: To Extract or Not to Extract?

While many people need to have their wisdom teeth removed, it’s not a hard and fast rule for everyone. In some cases, if the wisdom teeth are healthy, fully erupted, properly aligned, and can be cleaned as part of daily hygiene practices, they may not need to be removed.

Regular dental visits are crucial in this regard. Dentists can monitor the condition and position of your wisdom teeth using examinations and X-rays and can recommend extraction if it looks like they may cause problems.

Conclusion

Understanding wisdom teeth and their role in our dental health is crucial to maintaining our oral well-being. While the evolutionary need for these teeth has diminished, their potential to impact our dental health significantly has not. Regular dental check-ups are key in monitoring these late bloomers and ensuring they’re not causing more harm than good. Remember, when it comes to wisdom teeth, prevention and early intervention can save you a lot of discomfort and potential health issues down the line.

A Comprehensive Guide to Professional Teeth Whitening Procedures

It’s hard to ignore the allure of a bright, confident smile. One of the most sought-after dental treatments for achieving this is teeth whitening. Professional teeth whitening procedures have risen in popularity as they provide more reliable and quick results compared to over-the-counter products. This comprehensive guide will take you through the ins and outs of professional teeth whitening procedures.

What is Professional Teeth Whitening?

Professional teeth whitening is a procedure performed by a dental professional designed to lighten the color of your teeth. Over time, teeth can become stained due to various factors such as food, beverages (like coffee and red wine), tobacco use, medication, aging, and even genetics. 

Professional teeth whitening services typically involve the application of a high-concentration bleaching gel that’s activated with a specialized light or laser. This process can significantly lighten the color of your teeth, often in just a single visit.

Types of Professional Teeth Whitening Procedures

1. In-Office Whitening

In-office teeth whitening is the most effective and quickest method. A high-concentration peroxide gel is applied to the teeth after the gums have been protected with a paint-on rubber dam. The gel remains on the teeth for several intervals of 15 to 20 minutes. When combined with heat, light, or laser, the results can be dramatic and immediate.

2. Professionally Dispensed Take-Home Whitening Kits

These kits are a hybrid between in-office and over-the-counter whitening kits. They contain a lower-concentration peroxide gel that remains on the teeth for an hour or longer (often overnight). The lower the peroxide percentage, the longer it may safely remain on the teeth. The gel is applied to the teeth using custom-made bleaching trays resembling mouth guards.

3. Internal Whitening

Internal whitening is a method used for teeth that have been root-canal treated, meaning the staining is coming from inside the tooth. A peroxide gel is placed inside the tooth and left in place for a period of time. This type of whitening is typically done in conjunction with external whitening.

Benefits of Professional Teeth Whitening 

The most significant advantage of professional teeth whitening is its effectiveness. Professional procedures can remove deep stains that over-the-counter products can’t reach. They also offer faster results, often in just one appointment. 

Additionally, your dentist can tailor the procedure to your specific needs, adjusting the concentration of the whitening agent and treatment duration to achieve desired results while minimizing side effects such as tooth sensitivity.

What to Expect During and After a Whitening Procedure

During an in-office whitening treatment, your dentist will first clean your teeth and gums before applying a protective barrier to your gums. They’ll then apply the whitening gel to your teeth and use a special light or laser to activate the gel. You can expect the procedure to last about an hour.

After the treatment, you may experience some tooth sensitivity, which is a common side effect of teeth whitening. This sensitivity should subside after a few days. Your dentist may recommend a toothpaste for sensitive teeth if your teeth are particularly sensitive. It’s also recommended to avoid foods and drinks that can stain your teeth for at least 48 hours after the procedure.

Maintaining Your Whitened Teeth

To maintain your bright smile, you should continue to practice good oral hygiene by brushing twice a day, flossing daily, and regularly visiting your dentist. You should also limit consumption of staining substances such as tobacco, coffee, tea, and red wine.

Periodic touch-up treatments, either in-office or at home, are also beneficial in maintaining your results. Your dentist can advise.
