What exactly is DENTAL EROSION? What are Causes, Diagnosis, Prevention and Treatment of Dental Erosion?

TOOTH EROSION is a type of tooth wear. It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin.

Dental erosion is the most common chronic disease of children ages 5–17.

CAUSES:

The most common cause of erosion is by acidic foods and drinks. In general, foods and drinks with a pH below 5.0–5.7 have been known to trigger dental erosion effects.

EXTRINSIC (External) SOURCES: Acidic food and drink lowers the pH level of the mouth resulting in demineralisation of the teeth.

Examples include fruit juices, such as apple and orange juices, sports drinks, wine and beer. Carbonated drinks, such as colas and lemonades, are also very acidic and hence have significant erosive potential.

INTRINSIC (Internal) SOURCES: Intrinsic dental erosion, also known as perimolysis, is the process whereby gastric acid from the stomach comes into contact with the teeth.

Self-induced vomiting increases the risk of dental erosion by a factor of 5.5 compared to healthy controls.

DIGNOSIS: 

There are numerous signs of dental erosion, including changes in appearance and sensitivity.

SIGNS: include pain when eating hot, cold, or sweet foods. This pain is due to the enamel having been eroded away, exposing the sensitive dentin.

COLOR: Dental erosion can lead to two major tooth colour change - 

(1) a change of color that usually happens on the cutting edge of the central incisors. This causes the cutting edge of the tooth to become transparent. 

(2) A second sign is a yellowish tint on the eroded tooth. This occurs because the white enamel has eroded away to reveal the yellowish dentin beneath.

SHAPE: Teeth will begin to appear with a broad rounded concavity, and the gaps between teeth will become larger. 

COMPLICATIONS: Fillings may also appear to be rising out of the tooth.

One of the most severe signs of dental erosion is cracking, where teeth begin to crack off and become coarse.

PREVENTION:

TREATMENT:

If you’ve lost some of it, there are ways to fix it. The best approach depends on your situation.

Dental problems are disturbing , but a majority of them can be prevented or easily resolved. Brushing twice a day, flossing daily, eating properly and educating yourself about common dental problems and their causes can also helps in preventing dental problems. 1. TOOTH DECAY Tooth decay , also known as  dental caries  or  cavities , is the breakdown of teeth  due to acids made by bacteria.   You get them when a sticky bacteria, called plaque, builds up on your teeth, slowly destroying the hard outer shell, called enamel.  The cavities may be a number of different colors from yellow to black.  According to the World Health Organization (WHO) about 60 to 90% of kids worldwide   have cavities. SYMPTOMS: Pain, Tooth loss, Difficulty eating.  COMPLICATION: Inflammation around the tooth, tooth loss, Infection, or abscess formation.  DURATION: Long term  PREVENTION:   The best way to prevent tooth decay is by brush...

MOUTH ULCER / ORAL ULCER / MUCOSAL ULCER

Image
  A  mouth ulcer  is an ulcer that occurs on the mucous membrane of the oral cavity. The two most common causes of oral ulceration are local trauma (e.g. rubbing from a sharp edge on a broken filling or braces, biting one's lip, etc.) and aphthous stomatitis   ("canker sores"), a condition characterized by recurrent formation of oral ulcers for largely unknown reasons. EROSION :  is a superficial breach of the epithelium, with little damage to the underlying lamina propria.  MUCOSAL EROSION:  is an erosion which specifically occurs on a mucous membrane.  EXCORIATION:   is a term sometimes used to describe a breach of the epithelium which is deeper than an erosion but shallower than an ulcer. ULCERATION:   is a break in the skin or mucous membrane with loss of surface tissue and the disintegration and necrosis of epithelial tissues. Diagramatic representation of mucosal erosion (left), excoriation (center), ...

WHAT CAUSES TOOTH SENSITIVITY? HOW TO GET RID FROM SENSITIVITY?

Image
Sensitive teeth involve experiencing pain or discomfort to your teeth from   sweets, cold air, hot drinks, cold drinks, or ice cream . Some people with sensitive teeth even experience discomfort from brushing and flossing. Sensitive teeth can also be a sign of a cracked tooth or a ​tooth abscess, which needs to be treated by your dentist to prevent losing a tooth or getting an infection in your jaw bone. CAUSES: Various things can cause tooth sensitivity. Some of the most common causes include: Worn tooth enamel from using a hard toothbrush and brushing aggressively. Tooth erosion due to highly acidic foods and beverages. Tooth decay, worn, leaky fillings, and broken teeth that expose the dentin of your tooth. Gum recession that leaves your root surface exposed. Grinding your teeth at night. Post dental treatment sensitivity is common but temporary, especially with crowns, fillings, and tooth bleaching. SIGN AND SYMPTOMS: The pain is sharp and sudden, in response to an external sti...
