The Role Of Cavities And Fillings In Your Oral Health
Most people at one time in their life will face the issue of cavities and fillings . They are not inevitable, but just the same, many people will have to endure a filling at some point in their life. A cavity occurs when the tooth becomes decayed and leaves a hole in the tooth, exposing the nerve and the inner portion of the tooth. It is necessary for the dentist to treat the cavity with a filling to prevent any further decay of the tooth.
How Do Cavities Occur
The first thing that you should know about cavities and fillings is how they occur. When you know the cause of the problem, you can be more proactive about eliminating the need for fillings and an elimination of cavities in your future.
Improper dental hygiene is largely responsible for cavities and fillings. Removing the plaque from your teeth and keeping your mouth clean is the best preventative medicine to keeping cavities from happening. When plaque is not removed from the teeth and mouth, eventually the bacteria and acids will begin to attack the enamel on the teeth. Left unchecked, this decay can go even further to the dentin layer of your teeth.
Brushing and flossing are an important part of your oral health care routine. You should remember to brush after eating and floss to remove the food particles and plaque that is between your teeth and in areas where your toothbrush cannot reach.
Treatment For Cavities
The dentist will remove the decayed part of the tooth and fill it with a material that will protect the tooth from further decay and problems. The cavity must be filled to keep bacteria out of the area and food debris from becoming lodged in the cavity. All of the decayed tooth must be removed. Simply filling in the cavity is often not enough and the dentist will have to drill away damaged areas of the tooth to stop the spread of tooth decay.
There are a number of materials that are used for filling cavities . The dentist may use a lining to protect the nerve before the material is placed in the area. Some of the materials that are used for fillings are gold, porcelain , silver amalgam, or composite resins. The dentist will make his recommendation for the type of filling material that is used.
Avoiding Cavities And Fillings
Good oral hygiene will help you to avoid cavities and fillings. You should make sure that you follow the advice of your dentist and brush your teeth after every meal. At a minimum, you should be brushing your teeth for two minutes. This is a much longer time period than you might imagine. Check how long you typically brush your teeth and you will most likely find that you are far below the two-minute mark.
It is far easier to avoid cavities and fillings than it is to experience them because of the pain of a toothache. Practice good oral hygiene and you may never have to face the dentist’s drill again.

Nasal cavity cancer
Introduction: An area of the face which includes the protruding nose along with its nostrils and the structures inside the nose is called the nasal cavity. It is the air-filled space located behind the nose and above the throat. The nasal cavity and the paranasal sinuses (the hollow, air-filled spaces in the bones around the nose) serve to filter moisten and warm air before it travels down into the lungs. Nasal Cavity Cancer is a rare form of cancer that begins in the nasal cavity (the inside of the nose) which is the first chamber of the respiratory system. The most common form of nasal cavity cancer is squamous cell carcinoma which forms in flat, epithelial cells that line the nasal cavity. Prolonged exposure to chemicals or dust may increase the risk of developing nasal cavity cancer. Most types of nasal cavity infections are simply just infections or capillaries, which can cause frequent nose bleeds and will not lead to nasal cancer. Men are affected twice as often as women with nasal related cancers. Treatment: Nasal cavity cancer treatment depends on several factors such as the cancer stage, type and location, as well as the patient's age and general health. A malignant tumor in the nose can spread to any part of the body so any abnormal growth in, or around the nose must be reported to the doctor. Surgery is required for these kind of nasal cancers in order to remove the rumor . radiation and chemotherapy although a more uncommon practice for nasal cancer can also be used sometime. Chemotherapy and radiation therapy are used as an adjuvant treatment (following surgery) to help kill any remaining cancerous cells. Causes: Inhalation of the smoke , certain infections of the nasal cavity , frequently occuring nasal infections, low immunity system (easily catch disease) , have a history of cancer in family and if an individual breathes in sawdust regularly then he is more prone to get a nasal caity cancer. Continuous exposure to metals like nickel, chromium and other organic chemicals used in manufacturing greatly increase the risk of developing nose cancer. Symptoms: Early stage of nasal cavity cancer displays no signs or symptoms but in later stages the tumor grows quite large and spreads to other areas of the body. nosebleeds, persistent congestion, pain or pressure around the eyes or ears, one-sided nasal obstruction, frequent headaches, a runny nose, enlarged lymph nodes, facial numbness or tingling, pain in the upper teeth, or a growth/mass in the nose are some possible symptoms associated with nasal cavity cancer. Potential symptoms should not be neglected as early detection and treatment of nose cancer greatly improves survival rates. References: cancermba.com cancercenter.com cancer.stanford.edu see less

Dental cavities Guide
Causes, Incidence, And Risk Factors
Tooth decay is one of the most common of all disorders, second only to the common cold. It usually occurs in children and young adults but can affect any person. It is a common cause of tooth loss in younger people.
Bacteria are normally present in the mouth. The bacteria convert all foods -- especially sugar and starch -- into acids. Bacteria, acid, food debris, and saliva combine in the mouth to form a sticky substance called plaque that adheres to the teeth. It is most prominent on the back molars, just above the gum line on all teeth, and at the edges of fillings. Plaque that is not removed from the teeth mineralizes into tartar. Plaque and tartar irritate the gums, resulting in gingivitis and ultimately periodontitis.
Plaque begins to build up on teeth within 20 minutes after eating (the time when most bacterial activity occurs). If this plaque is not removed thoroughly and routinely, tooth decay will not only begin, but flourish.
The acids in plaque dissolve the enamel surface of the tooth and create holes in the tooth (cavities). Cavities are usually painless until they grow very large and affect nerves or cause a tooth fracture. If left untreated, a tooth abscess can develop. Untreated tooth decay also destroys the internal structures of the tooth (pulp) and ultimately causes the loss of the tooth.
Carbohydrates (sugars and starches) increase the risk of tooth decay. Sticky foods are more harmful than nonsticky foods because they remain on the surface of the teeth. Frequent snacking increases the time that acids are in contact with the surface of the tooth.
Symptoms
There may be no symptoms. If symptoms occur, they may include:
Tooth pain or achy feeling, particularly after sweet, hot, or cold foods and drinks
Visible pits or holes in the teeth
Signs And Tests
Most cavities are discovered in the early stages during routine checkups. The surface of the tooth may be soft when probed with a sharp instrument. Pain may not be present until the advanced stages of tooth decay. Dental x-rays may show some cavities before they are visible to the eye.
Treatment
Treatment can help prevent tooth damage from leading to cavities.
Treatment may involve:
Fillings
Crowns
Root canals
Dentists fill teeth by removing the decayed tooth material with a drill and replacing it with a material such as silver alloy, gold, porcelain, or composite resin. Porcelain and composite resin more closely match the natural tooth appearance, and may be preferred for front teeth. Many dentists consider silver amalgam (alloy) and gold to be stronger, and these materials are often used on back teeth. There is a trend to use high strength composite resin in the back teeth as well.
Crowns or "caps" are used if tooth decay is extensive and there is limited tooth structure, which may cause weakened teeth. Large fillings and weak teeth increase the risk of the tooth breaking. The decayed or weakened area is removed and repaired. A crown is fitted over the remainder of the tooth. Crowns are often made of gold, porcelain, or porcelain attached to metal.
A root canal is recommended if the nerve in a tooth dies from decay or injury. The center of the tooth, including the nerve and blood vessel tissue (pulp), is removed along with decayed portions of the tooth. The roots are filled with a sealing material. The tooth is filled, and a crown may be placed over the tooth if needed.
Expectations (Prognosis)
Treatment often saves the tooth. Early treatment is less painful and less expensive than treatment of extensive decay.
You may need numbing medicine (lidocaine), nitrous oxide (laughing gas), or other prescription medications to relieve pain during or after drilling or dental work.
Nitrous oxide with Novocaine may be preferred if you are afraid of dental treatments.
Complications
Discomfort or pain
Fractured tooth
Inability to bite down on tooth
Tooth abscess
Tooth sensitivity
Calling Your Health Care Provider
Call your dentist if you have a toothache.
Make an appointment with your dentist for a routine cleaning and examination if you have not had one in the last 6 months to 1 year.
Prevention
Oral hygiene is necessary to prevent cavities. This consists of regular professional cleaning (every 6 months), brushing at least twice a day, and flossing at least daily. X-rays may be taken yearly to detect possible cavity development in high risk areas of the mouth.
Chewy, sticky foods (such as dried fruit or candy) are best if eaten as part of a meal rather than as a snack. If possible, brush the teeth or rinse the mouth with water after eating these foods. Minimize snacking, which creates a constant supply of acid in the mouth. Avoid constant sipping of sugary drinks or frequent sucking on candy and mints.
Dental sealants can prevent some cavities. Sealants are thin plastic-like coatings applied to the chewing surfaces of the molars. This coating prevents the accumulation of plaque in the deep grooves on these vulnerable surfaces. Sealants are usually applied on the teeth of children, shortly after the molars erupt. Older people may also benefit from the use of tooth sealants.
Fluoride is often recommended to protect against dental caries. It has been demonstrated that people who ingest fluoride in their drinking water or by fluoride supplements have fewer dental caries. Fluoride ingested when the teeth are developing is incorporated into the structure of the enamel and protects it against the action of acids.
Topical fluoride is also recommended to protect the surface of the teeth. This may include a fluoride toothpaste or mouthwash. Many dentists include application of topical fluoride solutions (applied to a localized area of the teeth) as part of routine visits

Gingivitis
This is an inflammation of the gums, which happens due to bacterial infections or due to some disease conditions. The gums become tender and sore. There is no obvious pain, but when the gums are pressed, they will be painful and might even bleed. When plaque begins to build up on the teeth, it is an indication of a case of gingivitis coming on. Even some health conditions such as diabetes can bring on gingivitis. People who have inadequate diet, do not take care of their teeth, smoke and suffer stress often are likely candidates for this condition. However, this condition is not serious at all if it is diagnosed early. All symptoms of gingivitis can be easily reversed.
Bleeding Gums
Gums can bleed due to a variety of factors; in fact in most conditions gums will bleed. But this bleeding may not be apparent in all of these conditions. The dentists use a specific device known as a periodontal probe to determine whether or not gums are bleeding. Outwardly, this is manifested by the reddening of gums from their healthy pink color. Gums may become more sensitive and painful. If any such condition occurs, treatment becomes important because if left alone, it can cause more serious conditions later on, even culminating in the loss of teeth.
Periodontitis
Any condition of inflammation of the gums can be called as periodontitis . In milder cases it is painless, but in chronic cases it can be extremely painful and may cause loss of teeth. In most cases of periodontitis , the damage is not only to the gums but also to the surrounding tissues and bones. The teeth are also affected. The milder form of this gum disease is known as aggressive periodontitis, while the more serious form is known as chronic periodontitis. These diseases are not age-related, but older people seem to have this condition more than younger people. Also, women are more predisposed to periodontitis than men. Tooth loss usually occurs when periodontitis aggravates to the chronic level.
Prevention of Gum Disease
All gum diseases can be prevented if due care is taken right from the start. Proper dental hygiene is a must and there must be regularity in brushing and flossing. It is vitally important not to let food particles accumulate on the teeth, gums or the tongue. Hence, tongue cleaning also becomes important.
Any changes in the gums must be noted early on. This includes any kind of darkening of the color of the gums, because the darkening will not occur all over, all at once. Also, if the toothbrush shows signs of blood after brushing, it must not be neglected, even though the brushing might have been painless.
