Sensitive Teeth Causes: Common Reasons for Tooth Pain

 Ever bitten into an ice cream or sipped a hot coffee and felt a sudden, sharp jolt of pain in your teeth? If so, you’re not alone. Many people experience what’s known as sensitive teeth. It’s a common issue that can make everyday eating and drinking a real challenge. 

In this blog, we’re going to dive into the world of sensitive teeth causes to help you understand why your pearly whites might be protesting.

What Are Sensitive Teeth?

So, what exactly are sensitive teeth? Imagine your tooth like a tiny house. On the outside, you have a hard, protective layer called enamel. This enamel acts like the roof and walls, shielding the inner parts of your tooth from harm. Underneath the enamel is a softer layer called dentin. Dentin is full of tiny, microscopic tubes (think of them like tiny tunnels) that lead directly to the tooth’s nerve in the very centre.

When the protective enamel layer gets worn away or the gums (which cover the roots of your teeth) pull back, these tiny dentin tunnels become exposed. This means that hot, cold, sweet, or even acidic foods and drinks can reach the nerve much more easily. When they do, the nerve gets a shock, and that’s the sharp, sudden pain you feel. It’s your tooth’s way of saying, “Ouch!”

Common Causes of Sensitive Teeth

Now that we know what sensitive teeth are, let’s explore the various reasons why they might be feeling a bit grumpy. Understanding these causes of tooth sensitivity is the first step towards getting some relief.

1. Enamel Erosion and Sensitivity: This is a big one. As we mentioned, enamel is your tooth’s bodyguard. But sometimes, this bodyguard gets worn down. Why does this happen?

• Eating and Drinking Acidic Stuff: Think about your favourite fizzy drinks, fruit juices, or even some fruits like lemons and oranges. These can be quite acidic. Over time, the acids can slowly dissolve your enamel, making it thinner and less protective. It’s like a gentle but constant acid rain on your teeth.
• Aggressive Brushing: Brushing your teeth is good, but brushing too hard or with a toothbrush that has stiff bristles can actually wear away your enamel and even your gums. Imagine scrubbing a delicate surface with a harsh brush – it’s not going to end well!
• Teeth Grinding (Bruxism): If you grind your teeth, especially at night while you sleep, you’re putting a lot of pressure on them. This constant rubbing can wear down the enamel over time, just like sandpaper.
• Certain Medical Conditions: Some medical conditions, like acid reflux (where stomach acid comes up into your mouth), can also lead to enamel erosion. Eating disorders that involve frequent vomiting can also expose teeth to stomach acids.

2. Gum Recession and Tooth Sensitivity: Your gums play a vital role in protecting the roots of your teeth. The roots don’t have that hard enamel coating; instead, they’re covered by a softer layer called cementum. When your gums pull back, or “recede,” the cementum-covered root becomes exposed. And guess what’s under the cementum? More of those tiny dentin tunnels!

• Gum Disease (Periodontal Disease): This is a common culprit. Gum disease is an infection of the gums and bone that support your teeth. If left untreated, it can cause your gums to pull away from your teeth, exposing the roots.
• Aggressive Brushing (Again!): Yes, brushing too hard doesn’t just wear down enamel; it can also make your gums recede.
• Genetics: Sometimes, it’s just in your genes. Some people are more prone to gum recession than others.
• Smoking: Smoking is terrible for your gums and can contribute to gum recession.

3. Cavities (Tooth Decay): A cavity is basically a hole in your tooth caused by decay. When a cavity forms, it eats away at the enamel and can reach the dentin. Once the dentin is exposed, you’re going to feel sensitivity, especially to sweet things or hot and cold.
4. Chipped or Cracked Teeth: Accidents happen! If you’ve chipped or cracked a tooth, even a tiny crack you can’t see, it can expose the dentin underneath. This can lead to sudden sensitivity when you bite down or when the tooth is exposed to temperature changes.
5. Worn Fillings: Fillings are put in to repair cavities. But over time, old fillings can wear down, crack, or even fall out. This can leave the tooth vulnerable and expose the dentin, leading to sensitivity.
6. After Dental Treatments: Sometimes, you might feel temporary sensitivity after certain dental procedures, like having a filling placed, a crown fitted, or even after a professional clean. This usually settles down after a few days or weeks as your tooth recovers.

How to Diagnose Sensitive Teeth

If you’re experiencing tooth pain, it’s really important to see a dentist at Sutherland Dental. They are the best people to figure out what’s going on. Diagnosing sensitive teeth usually involves:

• Asking Questions: Your dentist will ask you about your symptoms – when do you feel the pain? What triggers it? How long does it last?
• Looking at Your Teeth: They’ll carefully examine your teeth and gums for signs of enamel erosion, gum recession, cavities, or cracks.
• Tapping Your Teeth: Gently tapping on your teeth can sometimes help pinpoint the sensitive tooth.
• Using a Dental Probe: They might use a small instrument to check for exposed dentin or decay.
• X-rays: X-rays can help reveal hidden cavities or other issues below the surface of your teeth and gums.

It’s important not to try and diagnose yourself. What feels like sensitivity could actually be a sign of a more serious problem.

Treatment Options for Sensitive Teeth

The good news is that there are many ways to get tooth sensitivity relief once you know the cause. Our dentist Sutherland will recommend the best course of action for you.

• Desensitising Toothpaste: These toothpastes contain special ingredients that help block the tiny dentin tubules, stopping the hot and cold from reaching the nerve. You need to use them regularly for a few weeks to notice a difference.
• Fluoride Treatments: Our Sutherland dentist can apply fluoride gels or varnishes to your teeth. Fluoride helps strengthen enamel and can reduce sensitivity.
• Bonding or Fillings: If the sensitivity is caused by an exposed root surface or a small cavity, your dentist might apply a tooth-coloured filling material to cover the area.
• Gum Grafts: In severe cases of gum recession, a gum graft might be recommended. This involves taking a small piece of tissue from another part of your mouth and attaching it to the receded gum line to cover the exposed root.
• Root Canal Treatment: If the sensitivity is severe and persistent, and other treatments haven’t worked, it might mean the nerve inside your tooth is damaged. In this case, a root canal might be necessary to remove the damaged nerve and stop the pain.
• Mouthguards: If teeth grinding is the cause, your dentist might suggest a custom-made mouthguard to wear at night. This protects your teeth from the grinding action.

Preventive Measures for Sensitive Teeth

Prevention is always better than cure, especially when it comes to your teeth! Here are some simple steps you can take to prevent sensitive teeth from bothering you in the first place:

• Brush Gently: Use a soft-bristled toothbrush and brush with gentle, circular motions. Avoid scrubbing hard.
• Use Fluoride Toothpaste: Choose a toothpaste that contains fluoride. Fluoride helps strengthen your enamel.
• Limit Acidic Foods and Drinks: Try to reduce your intake of highly acidic beverages like soft drinks, fruit juices, and energy drinks. If you do consume them, try to use a straw to minimise contact with your teeth.
• Rinse After Acidic Foods: After eating or drinking something acidic, rinse your mouth with water. This helps neutralise the acids. Don’t brush straight away, as your enamel will be softened by the acid and brushing too soon can cause more erosion. Wait at least 30 minutes.
• Address Teeth Grinding: If you suspect you’re grinding your teeth, talk to your dentist. They can offer solutions like mouthguards.
• Maintain Good Oral Hygiene: Brush twice a day, floss daily, and use an antiseptic mouthwash. This helps prevent gum disease and cavities, which are major contributors to sensitivity.
• Regular Dental Check-ups: See your dentist regularly for check-ups and professional cleans. This allows them to spot problems early and provide preventive care.

When to See a Dentist for Sensitive Teeth

While occasional mild sensitivity might be manageable with over-the-counter products, there are times when it’s crucial to see a dentist. Don’t delay if:

• The sensitivity is severe or constant.
• The pain doesn’t go away after a few days of using desensitising toothpaste.
• You notice swelling in your gums or face.
• You have a fever along with tooth pain.
• You suspect you have a cavity or a cracked tooth.
• The sensitivity is interfering with your eating, drinking, or daily life.

Remember, a dentist like dentist Sutherland can help you understand the specific causes of sensitive teeth for your pain and guide you towards the best tooth sensitivity relief. Early intervention can often prevent more serious problems down the track.
