What Is A Cavity?

Cavities are areas on the hard surface of your teeth that have been permanently damaged. Cavities often develop into tiny openings or holes on the teeth and can be caused due to several factors. This condition is also referred to as tooth decay or caries.

Cavities are one of the most common oral health problems. They are quite common across a wide age group, ranging from children and teenagers to older adults.

Read on to look at the common causes of cavities.

What Causes Cavities?

Cavities usually develop in various steps. They are:

  • Formation Of Plaque – Plaque is a layer of transparent and sticky film that coats your teeth. This can harden under or above your gumline to form tartar, which is even more difficult to be removed.
  • Attack By Plaque – The presence of acid in plaque can cause loss of minerals in the enamel of the affected tooth. This can cause your tooth to erode and develop tiny openings or holes on it, which is the first stage of cavities. If your enamel begins wearing away, the bacteria and acid from the plaque can reach the inner layer of your tooth, called the dentin. This progression results in sensitivity.
  • Continuation Of Destruction – Tooth decay can progress to the inner teeth material (pulp) that contains the nerves and blood vessels. Bacteria can irritate the pulp and may cause it to swell. The swelling of the pulp can cause the nerves to become pressed, thus causing pain and permanent damage.

Almost everyone with teeth is at risk of tooth decay or cavities. Other factors that may increase your risk of developing cavities are (2):

  • Location of the tooth – Tooth decay often affects the back teeth, your molars, and premolars.
  • Foods and drinks that may stick to your teeth for a long time like milk, ice cream, soda, or other sugary foods/drinks
  • Frequent snacking or sipping on sugary drinks
  • Feeding infants at bedtime
  • Poor oral hygiene habits
  • Dry mouth
  • Worn-out fillings or dental devices
  • Heartburn
  • Eating disorders like bulimiai  A serious, life-threatening eating disorder in which you consume large quantities of food in one sitting. or anorexiai  A serious psychological and eating disorder characterized by abnormally low body weight and fear of gaining weight.

Cavities in children also occur due to these factors, especially after eating foods with high sugar content and going to bed without brushing or flossing teeth.

As your cavities progress, they may exhibit the following symptoms.

Symptoms Of Cavities

  • Toothache that occurs without any cause
  • Tooth sensitivity
  • A mild to sharp pain while eating sugary, hot, or cold foods
  • Appearance of visible holes or pits in your teeth
  • Pain while biting down
  • Brown, black, or white stains on the surface of your tooth

A survey conducted on 193.5 million participants found that more than 1 in 5 adults within the had untreated caries. The prevalence of untreated caries was reported as 21.3%. It was most prevalent in those aged 30 through 39 years (25.2%) and 40 through 49 years (22.3%).

If you have noticed any of your teeth beginning to rot, it is high time that you treat them. If the cavity is not treated, the decay will eventually reach the tooth’s nerve tissue and the deepest layer of the tooth, necessitating either a root canal or tooth extraction to save your dentures. Keep scrolling to understand how to stop a cavity from getting worse.

Note: It is essential that you seek medical intervention to prevent permanent damage. The following home remedies may fix a cavity and/or reverse cavities only if the decay hasn’t penetrated the dentin, i.e., if it is in the pre-cavities stage.

Tooth decay, carries, or cavities all refer to the condition where the hard surface of the teeth is damaged. Plaque formation is a huge risk factor for developing cavities, though poor oral hygiene and sugary or sticky food intake can be equally responsible, among other factors. Cavities present symptoms such as increased tooth sensitivity, sharp pain while eating certain food items, toothache with no apparent cause, visible holes in the teeth, and stains on the surface of the teeth. Home remedies with ingredients like vitamin D supplements, fluoride toothpaste, sugar-free gum, etc., can get rid of cavities only if treated in the early stages. For cavities that have penetrated deep, medical attention is needed.
