The Causes of Teeth Sensitivity & How to Avoid it

Post by: Gerarda on 05 Dec 2022

Teeth sensitivity is caused by the exposure of the dentin, the layer of the tooth beneath the enamel. This can be caused by a variety of factors, including:

• Tooth decay
• Tooth erosion
• Worn fillings
• Brushing teeth too hard or with a toothbrush that has hard bristles
• Consuming acidic foods and drinks (such as citrus fruits and carbonated beverages)
• Grinding or clenching teeth
• Gum disease

To avoid tooth sensitivity, you can:

• Use a toothbrush with soft bristles and brush gently
• Limit consumption of acidic foods and drinks
• Use a mouthguard if you grind or clench your teeth
• Talk to your dentist about using a desensitizing toothpaste or fluoride gel
• Visit your dentist regularly for cleanings and check-ups
• If gum disease is identified, follow the treatment plan provided by your dentist

If you experience sensitivity that persists, it is important to make a dental appointment for a diagnosis and appropriate treatment.

13 Most Acidic Fruit

Post by: Gerarda on 21 Nov 2022

Tooth enamel is the outer layer of a tooth and is hard, shiny and white. While it is the hardest substance in the body, even stronger than bone, it is still fragile. Enamel is just a thin layer of minerals that cover the tissue inside the tooth, therefore, it needs proper care.

When enamel, that first layer of defense is worn away from a tooth, it exposes the underlying dentin that is yellowish in color. This is called enamel erosion. This erosion can cause tooth sensitivity, pain, discoloration, indentations in teeth and fractured teeth.

There are many causes of erosion in teeth, but the main culprits of erosion are acidic foods, drinks and bodily fluids – saliva. As teeth enamel erodes it becomes thinner which allows the yellower dentin that lies below the enamel to be more visible through the enamel.

You can stop further damage if it hasn´t already broken through to the layer of dentin by eliminating the foods that caused the erosion in the first place. Even though tooth enamel is very strong, as it doesn´t have any living cells, it is unable to repair itself once it is damaged so you may need tooth bonding or for more severe erosion, a crown or a veneer.

There are many causes of tooth erosion, but as fruit is consumed in such high amounts on a daily basis, below are the 13 most acidic fruits.

  • Lemon Juice
  • Limes
  • Blue Plums
  • Grapes
  • Pomegranates
  • Grapefruits
  • Blueberries
  • Pineapples
  • Apples
  • Peaches
  • Apricots
  • Oranges
  • Tomatoes

Prevent Enamel Erosion

  • Eat cheese after eating fruit as it raises the pH levels in your mouth and increases saliva production.
  • Avoid sucking on lemons or any highly acidic fruit.
  • Use a straw when drinking fruit juices as it keeps the juice from coming in contact with your teeth.
  • Rinse your mouth with water after eating fruit to dilute the acids and wait for 30 minutes to brush to give the dentin time to resettle.
  • Brush with fluoride toothpaste.

Visit your dentist regularly to discuss ways to maintain a healthy smile. Practice good oral hygiene.

Fluoride Facts and Myths

Post by: Gerarda on 02 May 2022

Fluoride is a naturally occurring mineral that is commonly added to drinking water and toothpastes to help prevent tooth decay. It is also found in many foods and drinks.

Facts about fluoride:
• Fluoride helps to strengthen tooth enamel and make it more resistant to decay.

• Fluoride is effective in preventing tooth decay in both children and adults.

• Fluoride is safe to consume when used in the appropriate amounts.


Myths about fluoride:
• Fluoride is not safe to consume.

• Fluoride is not effective in preventing tooth decay.

• Fluoride causes cancer and other serious health problems.

It is important to note that fluoride is safe to consume when used in an appropriate way and quantity. Excessive fluoride intake can cause dental fluorosis, which is a cosmetic condition that causes discoloration and/or mottling of the teeth, but it is not linked to cancer or other serious health problems.

Ask your dentist or dental hygienist at your next dental examination / dental check-up about the use of fluoride.

Tooth Enamel Erosion and How to Prevent it

Post by: Gerarda on 19 Apr 2021

Even though you have the body’s hardest tissue covering your teeth, enamel, it is still very susceptible to damage especially from crunching or grinding hard substances, consuming acidic drinks, or chipping from opening a bottle with your teeth or biting your fingernails.

Enamel covers the crown of a tooth and is the only part visible outside the gum. Enamel serves a function of protection, providing a layer of insulation against temperatures and chemicals. If you have a tooth that has eroded you can have sensitivity for hot or cold when eating and drinking. Breathing cold air or eating sweets can also give you that same sensitivity. Once the tooth has eroded it leaves openings for the sensitivity to get through to the layer of tooth that contains the nerve fibers.

What causes tooth enamel erosion?
Eating too much food or drink containing sugar and acids erodes the enamel on teeth. Normal bacteria in your mouth thrive on sugar and unless you maintain good oral hygiene, bacteria are left to feed on the sugar which wreaks havoc on your teeth.

Tooth enamel erosion can be caused by the following:
• Soft drinks & fruit drinks
• Sour foods or candies – any food that tastes sour indicates the presence of an acid
• Foods high in sugar and starches – bread, pasta, rice, couscous, potatoes, breakfast cereals, oats and other grains
• Bulimia or alcoholism – frequent vomiting can erode the tooth enamel
• Dry mouth or low saliva flow (xerostomia)
• Environmental conditions – grinding (bruxism), wear and tear, stress
• Abrasion – brushing your teeth too hard or using a hard toothbrush
• Acid reflux disease (GERD) or heartburn
• Gastrointestinal problems
• Medications (antihistamines, aspirin, vitamin C)

How to avoid tooth erosion?
• Limit the amount of acidic food and drink you consume. If you are having a soft drink or fruit juice then have a glass of water or milk after to rinse your mouth or eat a piece of cheese.
• Drink water throughout the day.
• Use a soft toothbrush.
• Use fluoride toothpaste.
• Get treatment for any health conditions.
• Ask your dentist about sealants or dental bonding to prevent tooth erosion.

What to do if I have tooth erosion?
The tooth needs treatment in the form of tooth bonding or depending on the amount of tooth substance lost, it may need a veneer or a crown to protect it from further damage.

Tooth Enamel and Erosion

Post by: Gerarda on 08 Aug 2019

What is tooth enamel?
Tooth enamel is that hard, shiny layer of material which protects your teeth against decay. It is the layer of material that you are to brush and floss on a daily basis. To be more precise, it is hydroxyapatite, a translucent calcium phosphate. Suffice it to say enamel is the hardest mineral element in your body, even harder than bone. Don´t be fooled though as it still can be damaged.

What causes enamel to be damaged or eroded?
• Poor oral hygiene
• Acidic food & drinks (lemon juice, limes, grapefruits, grapes, pineapples, pomegranates, blueberries) to name a few
• Soft drinks in excess
• High sugar and starch diet
• Teeth grinding – wears away the enamel and leaves the dentin exposed
• Medications (antihistamines, decongestants, high blood pressure medications (including diuretics & calcium channel blockers), antidepressants, sedatives, pain medications, antacids
• Dry mouth – xerostomia, where the saliva glands don´t make enough saliva to keep the mouth wet. Many times this is a side effect of medication or radiation therapy.
• Acid reflux that occurs more than a couple of times a week
• Gastrointestinal problems – repeated vomiting from GI problems or eating disorders

What does tooth erosion look or feel like?
When your teeth become rough and irregular, or serrated like a saw blade you know the enamel has eroded. Essentially you reshape your teeth. You can experience sever sensitivity to both cold and hot temperatures and to sweets. You can also feel a shooting pain through one or more teeth so much so that it makes your eyes squint.

Can tooth erosion be repaired?
Once tooth enamel is gone, it´s gone. Teeth need to be rebuilt with composite restorations, crowns or veneers. The advantage of composite restorations is that it is a comparatively inexpensive and a conservative way to restore teeth. The result is immediate. More extensively damaged teeth might necessitate a porcelain veneer or porcelain crown.

You only get one set of permanent teeth; therefore, you might as well look after them. They are not meant to bite off thread or to open a bottle cap in a pinch. Your teeth need to be healthy as they not only serve to make us look good, but they also aid in digestion. As your mouth is the beginning of the digestive system it stands to reason that if you have digestive problems then you look to the overall health of your mouth as well as your stomach to determine the problem.

Begin by looking at your teeth and see whether any of the above symptoms are similar to yours. If they are then you know what to do. Call your dentist for a check-up.
