Why Wisdom Teeth Need to Go: Understanding the Extraction Process

Your third molars, better known as wisdom teeth, are usually the last to show up, often during young adulthood. Extraction becomes necessary when they don’t grow in properly. For many people, these teeth don’t have enough space to grow in properly. When they get stuck, shift other teeth, or lead to infections, your dentist may recommend removing them.

Wisdom tooth extraction in St Catharines, ON, is a routine step many patients take to stay ahead of oral health problems.

Why Wisdom Teeth Are Often Removed

While some people have enough space for wisdom teeth to grow in normally, most don’t. Common reasons for removal include:

  • They’re impacted: The teeth stay trapped under the gums or bone, often growing in sideways.
  • They’re crowding other teeth: Even if they come in straight, they can push against nearby molars.
  • Gum infections: If a wisdom tooth doesn’t fully break through the gum, it may trap debris, which can lead to gum tenderness and recurring inflammation
  • Cavities: These molars are hard to reach with a toothbrush and floss, so decay is more likely.
  • Cyst formation: Fluid-filled sacs can develop around impacted teeth, sometimes damaging the bone or nearby roots.
  • Ongoing gum issues: Redness, tenderness, or gum pocketing near the back of your mouth may be linked to these molars.

If your dentist sees signs that these risks are building, they may suggest emergency teeth removal, even before symptoms start.

How to Know If Your Wisdom Teeth Should Come Out

You don’t always feel wisdom teeth problems right away, but your mouth often gives you hints. Some signs to watch for:

  • Your jaw might feel sore or tight, especially near the back where wisdom teeth come in.
  • You could notice tenderness, redness, or puffiness around the gums behind your last molars.
  • It may become harder to open your mouth all the way without discomfort.
  • A lingering bad taste or breath that doesn’t improve with brushing can be a sign something’s not right.
  • Some people feel headaches or a dull ache that seems to travel toward the ears.
  • Swelling that comes and goes in the same area might mean the tooth is trapped or irritated.

If you notice these issues, it’s worth booking a dental visit to find out what’s going on beneath the surface.

What the Extraction Process Looks Like

Wisdom tooth pulling near you usually starts with a consultation. Your dentist will check your mouth, review any symptoms, and take X-rays to see how the teeth are positioned.

Anesthesia and Comfort Options

Depending on the situation, your dentist may recommend:

  • Local anesthesia (numbing the area)
  • Oral sedation (to help you relax)
  • IV sedation (for more complex removals)

Simple vs. Surgical Removal

  • Simple extraction: Used when the tooth has fully erupted. It’s gently loosened and removed.
  • Surgical extraction: If the tooth is still under the gums or bone, a small incision is made, and the tooth may be sectioned into pieces before removal.

The entire visit usually takes under 90 minutes. If sedation is used, you’ll need a ride home and time to rest afterward.

What Recovery Feels Like, and How to Heal Well

The first few days after wisdom tooth removal are all about rest and care. Here’s what to expect:

Day One

  • Use gauze to manage bleeding and rest with your head slightly elevated.
  • Avoid hot drinks, alcohol, and smoking.
  • Place a cold compress on your cheek to help ease swelling.

Days Two and Three

  • Go for smooth, soft foods after your extraction. Think along the lines of yogurt, oatmeal, or mashed veggies.
  • A light rinse with warm salt water can soothe the gums and keep the site clean.
  • Avoid vigorous rinsing or spitting, which can disrupt healing.

Ongoing Recovery

  • Brush carefully, staying clear of the surgical site.
  • Don’t use a straw; suction can pull out the healing clot.
  • Skip intense exercise for a few days.

Swelling usually peaks within 48 hours, then eases. Most patients feel well enough to return to their routine within 5–7 days. If anything feels off, like new pain, swelling, or a bad taste, contact your dental office.

FAQs About Wisdom Teeth Removal

You’ll likely need a couple of days off to rest and recover. If your job involves talking a lot or physical activity, plan for a bit more downtime.
