Dentin Exposure: Causes and Prevention

The dentin is in the outer layer of the tooth structure, sitting underneath your enamel. Its function is to protect the nerve-filled pulp, which is also protected by the enamel coating. Since the dentin isn’t as hard as the enamel and contains nerve endings, you may experience sensitivity when it’s exposed. Keep reading to find out its causes and how you can prevent it. 

Causes of Dentin Exposure

One of the ways to prevent dentin exposure is to know how it’s exposed. 

Teeth Grinding

Clenching and grinding your upper and lower teeth together eventually leads to chips and cracks. While this condition is caused by malocclusion and stress, it also occurs during sleep. Prolonged grinding results in a thinning enamel, exposing the dentin as a result. 

We suggest speaking with a professional to help you address this issue. Your dentist may recommend getting a nighttime mouth guard to prevent tooth grinding. 

Gum Recession

Poor dental hygiene can eventually lead to serious dental problems such as gingivitis. This occurs when you don’t regularly brush and floss your teeth. Food debris can get stuck in between your teeth, leading to the accumulation of dental plaque. 

Plaque is a sticky bacteria that produce acid, destroying your tooth enamel in the long run. When not addressed, plaque can lead to gingivitis. As a result, your gums may recede, exposing you to more infection. 

Brushing Too Much

It’s recommended to use a soft-bristled toothbrush with multi-layer bristles for efficient brushing. Using a hard-bristled toothbrush and brushing with too much force can damage the enamel and cause dentin exposure. Soft toothbrushes contain less densely packed bristles, allowing them to bend easily and making them gentler on gums and teeth. 


The discoloration is caused by tannins, a property usually found in coffee or wine, and certain fruits such as peaches and dark berries. This could eventually lead to exposed dentin and make your teeth yellow. Speak with a dentist in Coal Harbour for a dental checkup. We can help you alleviate the problem and prevent more damage. 

How to Prevent Dentin Exposure

When you’re experiencing increased tooth sensitivity, this could indicate a dentin exposure. You need to see a dentist in Vancouver ASAP for a checkup. 

You can prevent dentin exposure by wearing a mouthguard to give you a more comfortable night’s sleep. Reduce your sugar intake and use a soft-bristled toothbrush when brushing your teeth. Make sure to also floss twice a day to ensure your mouth stays clean.

Dental Veneers: Cavity protection

Dental Veneers: Cavity protection

Having veneers from a competent Dentist in Coal Harbour will give you the beautiful, flawless smile you’ve always wanted. Nonetheless, it’s important to remember that veneers don’t make your teeth invincible. They can be more susceptible to cavities and other damage if you don’t care for them properly. That’s why it’s important to practice the following practices to prevent cavities under veneers.

Practice Good Oral Hygiene

Good oral hygiene is essential whether or not you have veneers. Brushing regularly helps prevent plaque and bacteria from accumulating and hiding under the veneers, where they will cause decay and gum disease. Dentists in Vancouver advise brushing regularly but not too harshly lest you damage the veneer or your gums. They also encourage you to floss at least once daily with Flouride-based mouthwash.

Avoid Sugary Foods and Drinks

Sugar is one of the main culprits in cavities. As such, limiting your intake of sugary foods and drinks is crucial in preventing cavities under your veneers. Ideally, opt for water or unsweetened beverages instead of sugary drinks. Snacking on healthy foods like fruits and vegetables rather than candy or cake is also a good idea.

Don’t smoke

Smoking is terrible for your teeth. Besides causing bad breath, it also supports the growth of bacteria, tartar and plaque accumulation inside the veneers. These substances lead to cavities, decay and eventually tooth loss if not dealt with by a dentist in Vancouver. Smoking is one of the leading causes of tooth loss in adults. If you must smoke, be extra diligent about brushing and flossing your teeth. You may also want to consider quitting smoking altogether.

Regular Dental Visits

Regular dental checkups are important for people of all ages, but it is especially critical for those who have veneers. Quite confusing? Veneers are designed to be durable and long-lasting, so why incur the extra expense of dental visits? The truth is, regular dental visits are essential for maintaining good oral health when you have veneers and for good reason.

During a dental visit, Dentist in Coal Harbour will assess the health of your teeth and gums and clean away any plaque or tartar that has built up to prevent cavities. This is important for preventing gum disease and maintaining the cosmetic appearance of your veneers. In addition, the dentist will be able to identify any potential problems early on before they have a chance to cause serious damage.

Getting Dental Xrays

X-rays are an important tool that dentists use to help identify cavities. By looking at the shadows that the X-rays create, dentists can see what’s beneath the veneer and see if there is a missing tooth enamel or where there are areas of decay. This information is essential for providing proper treatment and preventing further damage. In addition, X-rays can also help to identify other problems, such as tumors or impacted teeth. As a result, they play an important role in maintaining oral health, especially for people with veneers.

Key Takeaway

If you’re considering getting veneers, good oral hygiene, regular dental checkups and avoiding sugar will help in preventing cavities under them. Quiting smoking or stepping up your oral hygiene will also be a point plus. After all, veneers are basically just a thin layer of porcelain that’s bonded to your teeth, so it’s important to make sure that they’re well taken care of.

Sleep Apnea Treatment, Vancouver: 5 Questions to Ask Your Dentist

Over 5 million Canadians have been diagnosed with sleep apnea or are at a high risk of developing the condition. Are you one of them?

If so, you probably have tons of questions about your health and potential treatments. And, your dentist is the first person you should ask!

Read on for 5 essential questions that you should get answered immediately, plus essential tips on finding the best sleep apnea treatment in Vancouver.

1. What Is Sleep Apnea?

Sleep apnea is actually a complex condition that comes in multiple varieties and can impact patients of all ages. Simply put, it’s a serious medical concern that can cause you to stop breathing while you sleep.

Many risk factors like obesity and smoking can increase your chances of developing sleep apnea. But, other factors like nasal congestion and genetics can also up your risk.

2. How Can I Tell if I Have Sleep Apnea?

If you have symptoms of sleep apnea, like loud snoring, gasping for air while sleeping, morning headaches, or an extremely dry mouth when you wake up – you might have sleep apnea.

But, the best way to find out for sure is to visit your dentist for an evaluation.

3. Is Sleep Apnea Dangerous?

Depending on how severe the condition has become, the effects of sleep apnea can actually be quite dangerous.

While it might seem that your snoring is little more than an annoyance, you might actually be experiencing episodes of breathlessness while you sleep. This can cause a wide variety of secondary symptoms – and it can even put your life in danger.

4. What Are My Options for Treatment?

If you came here wondering, “can sleep apnea be treated?” – you’re in luck. It can!

Dental treatments can often help ease the symptoms. And, in some cases, surgery can be used to widen or reinforce the airway. Other patients may benefit from the use of a CPAP machine, used to maintain positive pressure in the airway and keep you breathing.

5. What’s the Difference Between Central and Obstructive Sleep Apnea?

Obstructive sleep apnea is the most common condition. This medical concern arises when your throat muscles relax, allowing your airway to close.

Central sleep apnea, by contrast, takes place when your brain doesn’t send the proper signal to the muscles that control your body’s breathing.

A third, less common condition called complex sleep apnea syndrome, sometimes called treatment-emergent central sleep apnea, is diagnosed when a patient has both obstructive sleep apnea and central sleep apnea.

How Plaque and Tartar Differ and How Each Affects Your Teeth

The Differences Between Plaque and Tartar

How Plaque and Tartar Differ and How Each Affects Your Teeth and Gums

Plaque and tartar are related but they are not the same thing. You can still develop either with good oral hygiene, but the better you take care of your teeth and gums, the less chance you will have for periodontal disease and other dental problems.


Plaque on your teeth comes from the bacteria in the food you eat and liquids you drink. When you go for hours without brushing your teeth, like when you’re sleeping, you might feel like something rough and filmy is on your teeth when you wake up. There is something there and that something is plaque. Too much plaque can contribute to cavities, bad breath, and infected gums.

Some things that can contribute to the growth of plaque on your teeth include some medications, breathing through your mouth, and smoking. The longer you go between teeth cleanings, the worse your plaque will get. It can go down under your gums and form tartar. The best way to keep plaque to a minimum is to brush and floss your teeth as directed by your dentist and try to have the best oral hygiene you can.


Tartar is caused by a buildup of plaque on your teeth and often down below the gum level. Tartar is plaque that has been in your mouth long enough to harden. This makes it very difficult to remove and requires the hygienist to use special tools to remove it. These tools are sharp and pointed, but the hygienist is trained to use them carefully to do the job. Plaque and tartar, alone or together, can be a major cause of bleeding gums.

Root Planing and Scaling

Part of good oral hygiene in older patients is to undergo scaling and root planing. They are similar methods of cleaning up plaque and tartar but the depth at which they clean is different. Scaling your teeth is when the hygienist scrapes buildup off of your teeth above your gum line. If plaque and tartar are not too extensive, it might be able to be done in one visit. It is not uncommon, though, to have the procedure done in multiple visits.

Root planing goes down past the gum line to clean the plaque and tartar that has likely been there for decades. Root planing and scaling are major steps in the fight against periodontal disease. If you already have gum disease, these procedures can help to reverse it and get you back on track to have a healthy mouth.

Patients who have diabetes often suffer from dry mouth which can contribute to plaque, tartar, and periodontal disease. If you do have diabetes, it is very important to discuss your oral hygiene habits with your dentist to help maintain your overall health.

General Dentist vs. Cosmetic Dentist

At least 74.7% of Canadians see a dentist every year. They recognize how important oral health is and the necessity of finding a professional to help maintain it.

If you’re looking for a dentist in Cole Harbour, you may be overwhelmed by all the different types you have to choose from. They may have any number of different specialties with confusing names.

Cosmetic and general dentists are two of the most common and cover a wide range of services. Read on to learn the differences between them and how to find the best one.

General Dentist

If you start looking for a dentist in Cole Harbour, a general dentist is one of the first types you’ll find. They provide for all your basic dental care needs, including:

  • Diagnosing and treating oral diseases
  • Cleanings
  • Oral cancer screenings
  • Examining and interpreting x-rays
  • Filling cavities
  • Tooth extractions
  • Root canals
  • Fitting mouthguards and sealants
  • Fluoride treatments

The minimum educational requirement is obtaining one of 2 degrees; DDS or Doctor of Dental Surgery or DMD or Doctor of Medicine in Dentistry. They’re basically the same, but universities may use one title or the other.

A general dentist may also specialize in certain areas. There are several recognized specialties, including:

  • Dental anesthesiology
  • Dental public health
  • Endodontics
  • Oral and maxillofacial pathology, radiology, or surgery
  • Oral medicine
  • Orofacial pain
  • Orthodontics and dentofacial orthopedics
  • Pediatric dentistry
  • Periodontics
  • Prosthodontics

Cosmetic Dentist

Cosmetic dentists need a DDS or DDM degree, just like a general dentist. They can provide many of the same dentistry services such as x-rays, cleanings, and cavity fillings.

The difference is that they have the extra education and experience to complete additional procedures that will improve the look of your smile. These include:

  • Teeth whitening
  • Implants, crowns, and bridges
  • Teeth bonding
  • Veneers
  • Inlays and onlays
  • Dentures

Cosmetic dentistry isn’t a recognized specialty, but it can be learned through a specialized training course. It can take years of extra work but patients know they can trust them with the look of their smile.

Cosmetic treatments are more than just a vanity project. They can also have several benefits for your oral health. They prevent issues such as damage to your teeth or jaw bone or digestive problems from failure to chew your food.

Approximately 64.6% of Canadians have dental insurance to help cover all or part of their expenses. Most policies don’t cover cosmetic procedures unless they help restore or protect your teeth.

Finding a Dentist in Cole Harbor

Finding a dentist with experience in the procedures you need can be difficult, but knowing the differences in their specialties helps you choose the right one.

General dentistry covers the types of services most patients think of when they think of dental care. This includes cleanings, extractions, and cavity fillings.

Cosmetic dentists focus on improving the look of your smile with elective procedures such as whitenings, implants, and crowns.
