What is Dental Caries (Cavities) ?


Dental caries is the medical term for tooth decay or cavities. It is caused by specific types of bacteria. They produce acid that destroys the tooth's enamel and the layer under it, the dentin.

Many different types of bacteria normally live in the human mouth. They build up on the teeth in a sticky film called plaque. This plaque also contains saliva, bits of food and other natural substances. It forms most easily in certain places. These include:


  • Cracks, pits or grooves in the back teeth
  • Between teeth
  • Around dental fillings or bridgework
  • Near the gum line

Some of the plaque bacteria turn sugar and carbohydrates (starches) in the foods we eat into acids. The acids dissolve minerals in the hard enamel that covers the tooth's crown (the part you can see). The enamel erodes or develops pits. They are too small to see at first. But they get larger over time.

Acid also can seep through pores in the enamel. This is how decay begins in the softer dentin layer, the main body of the tooth. As the dentin breaks down, the enamel over it can collapse, forming a cavity.

If the cavity is not fixed, bacteria will get into the tooth's inner layer. This contains the soft pulp and sensitive nerve fibers.

Tooth roots exposed by receding gums also can develop decay. The root's outer layer, cementum, is not as thick as enamel. Acids from plaque bacteria can dissolve it rapidly.

No one really knows what causes the pain people get with cavities that have not entered the pulp. Theories include:


  • Inflammation caused by bacteria
  • Exposure of the root surface
  • Imbalance of fluid levels in tiny openings called tubules inside the dentin

Symptoms
Early caries may not have any symptoms. Later, when the decay has eaten through the enamel, the teeth may be sensitive to sweet, hot or cold foods or drinks.

Dry Mouth a Common Oral problem


We all need saliva to moisten and cleanse our mouths and digest food. Saliva also prevents infection by controlling bacteria and fungi in the mouth. When we don't produce enough saliva, our mouth gets dry and uncomfortable. Fortunately, there are many effective treatments for dry mouth.

What Causes Dry Mouth?

There are several causes of dry mouth, also called xerostomia. These include:


  • Side effect of certain medications. Dry mouth is a common side effect of many prescription and nonprescription drugs, including drugs used to treat depression, anxiety, pain, allergies, and colds (antihistamines and decongestants), obesity, acne, epilepsy, hypertension (diuretics), diarrhea, nausea, psychotic disorders, urinary incontinence, asthma (certain bronchodilators), and Parkinson's disease. Dry mouth can also be a side effect of muscle relaxants and sedatives.
  • Side effect of certain diseases and infections. Dry mouth can be a side effect of medical conditions, including Sjögren's syndrome, HIV/AIDS, Alzheimer's disease, diabetes, anemia, cystic fibrosis, rheumatoid arthritis, hypertension, Parkinson's disease, stroke, and mumps.
  • Side effect of certain medical treatments. Damage to the salivary glands, the glands that produce saliva, for example, from radiation to the head and neck and chemotherapy treatments for cancer, can reduce the amount of saliva produced.
  • Nerve damage . Dry mouth can be a result of nerve damage to the head and neck area from an injury or surgery.
  • Dehydration . Conditions that lead to dehydration, such as fever, excessive sweating, vomiting, diarrhea, blood loss, and burns can cause dry mouth.
  • Surgical removal of the salivary glands.
  • Lifestyle. Smoking or chewing tobacco can affect saliva production and aggravate dry mouth. Continuously breathing with your mouth open can also contribute to the problem.




What Are the Symptoms of Dry Mouth?

Common symptoms of dry mouth include:

  • A sticky, dry feeling in the mouth
  • Frequent thirst
  • Sores in the mouth; sores or split skin at the corners of the mouth; cracked lips
  • A dry feeling in the throat
  • A burning or tingling sensation in the mouth and especially on the tongue
  • A dry, red, raw tongue
  • Problems speaking or difficulty tasting, chewing, and swallowing
  • Hoarseness, dry nasal passages, sore throat
  • Bad breath



Why Is Dry Mouth a Problem?

Besides causing the aggravating symptoms mentioned above, dry mouth also increases a person's risk of gingivitis (gum disease), tooth decay, and mouth infections, such as thrush.

Dry mouth can also make it difficult to wear dentures.

How Is Dry Mouth Treated?

If you think your dry mouth is caused by certain medication you are taking, talk to your doctor. He or she may adjust the dose you are taking or switch you to a different drug that doesn't cause dry mouth.

In addition, an oral rinse to restore mouth moisture may be prescribed. If that doesn't help a medication that stimulates saliva production, called Salagen, may be prescribed.

Other steps you can take that may help improve saliva flow include:

  • Sucking on sugar-free candy or chewing sugar-free gum
  • Drinking plenty of water to help keep your mouth moist
  • Protecting your teeth by brushing with a fluoridetoothpaste, using a fluoride rinse, and visiting your dentist regularly
  • Breathing through your nose, not your mouth, as much as possible
  • Using a room vaporizer to add moisture to the bedroom air
  • Using an over-the-counter artificial saliva substitute

How to brush teeth properly you must know


 Lets Know how to Brush your teeth properly

knowing how to brush your teeth properly is very important to prevent conditions such as gingivitis and tooth decay. Incorrect brushing technique can also lead to tooth abrasion, a condition in which the surface of the tooth is worn away. The number one cause of tooth abrasion is from a toothbrush. The delicate gum tissue is also at risk for damage from the toothbrush bristles, causing tooth sensitivity from exposed root surfaces. Follow these instructions, and learn how to brush your teeth properly.

This technique is also recommended when assisting a child or someone who needs help with their brushing.


Difficulty: Easy
Time Required: Two Minutes

Here's How:


  • Apply a thin strip of toothpaste on your premoistened toothbrush.
  • Start with the upper left molars (back teeth) concentrating on the front surface of the tooth; you will be working in a clockwise direction from there. The average toothbrush head will cover 2 to 3 teeth at a time.
  • Hold the toothbrush parallel to your teeth, and point the bristles in the direction of the tissue, so they are resting slightly below the gumline. Apply slight pressure to the bristles, so they are slightly bent.
  • Gently move the brush in a circular motion for approximately 20 brush strokes, or roughly 10 seconds.
  • When brush strokes are complete, roll the bristles away from the gum tissue in a sweeping motion.
  • Continue the above steps until all of the front surfaces of the top and bottom teeth have been cleaned.
  • Moving on to the inside surfaces of the teeth, repeat steps 2 to 5 for the upper and lower premolars and molars.
  • When you are ready to clean the inside surface of the front teeth, known as the lingual surface, take the tip of the toothbrush, and in a flicking motion, direct the toothbrush from the gumline down. Do this 2 to 3 times.
  • Follow step 8 for the inside of the lower front teeth, but this time the flick will be directed up, again, away from the gumline. Do this 2 to 3 times.
  • Brush the biting surface of the upper and lower premolars and molars.
  • Gently brush your tongue and the inside of your cheeks.
  • Finish by rinsing with water or mouthwash.

Tips:

Always brush twice a day, preferably first thing in the morning and again right before you go to sleep. Try not to eat or drink anything once you have brushed in the evening.
When brushing someone else's teeth, try to stand behind them so you are looking down on their mouth. This will allow easier access to the mouth and a better view of their teeth. If they are taller than you, have them sit in a chair.
Replace your toothbrush every three months or when you notice the bristles starting to bend and look worn out. Always replace your toothbrush after you recover from a cold or the flu.
The above steps are suitable for use with an electric toothbrush, although the final roll may be eliminated if using a round oscillating brush head.
When brushing the inside surfaces of the upper and lower teeth (steps 8 and 9), try to avoid standing too close to your mirror, as the flick will usually cause some spray.

What You Need


  • An extra soft or soft bristled manual toothbrush.
  • Your choice of toothpaste. One that contains fluoride is preferred.
  • Water or mouth rinse.
