There is no substitution for a natural healthy tooth. Dental fillings are intended to replace tooth structure and restore a tooth damaged by decay (a cavity) back to its normal function and shape. Silver (amalgam) and tooth-colored (composite) fillings last a long time, though they can develop decay when the integrity is compromised by open margins, fracture, or recurrent decay. In this blog, we discuss the signs and symptoms that indicate your filling may need to be replaced in order to prevent further complications.

Amalgam fillings are made of an alloy (mixed metals) that expands and contracts. They have no bonding properties, and so to place an amalgam filling, the hole in the tooth may need to be larger. Because of these two factors, fractures frequently occur. There are three types of cracks that are commonly associated. Craze lines are superficial with no treatment needed. Fractures extend along other parts of the tooth and may require a filling replacement or crown. Cracks extend toward the root and can require a root canal and crown or, if too severe, extraction.

A filing needs to be sealed to the tooth. If the seal between the tooth and the filling breaks down, food debris and bacteria can seep down under the filling and cause recurrent decay. If the decay is treated early, replacing the filling is adequate. If not, a crown and even a root canal may be needed. The biggest mistake you can make is waiting to do something about a broken or unsealed filling until it is painful. Doing this will only make the treatment more involved and often times more expensive.

Regular dental exams and X-rays are used to evaluate dental fillings. You will not be able to tell on your own when your fillings start to fail. Just as a car mechanic will change the oil, correct your alignment, or change your tires, a dental checkup will help you identify small concerns to fix as you go in order to avoid a critical emergency.

Pay attention to any bite or temperature sensitivity in teeth that have fillings. This can be an indicator for some of the problems listed above. You know your teeth better than anyone. Your observations are most valuable when evaluating a filling for replacement. If replacement is needed, know you are doing what is best to prevent future dental calamities and make an appointment to see Dr. James Robson.

When acids are allowed to erode tooth enamel long enough to leach calcium and other minerals from your enamel and dentin, a process called demineralization occurs. This rapidly leads to tooth decay unless reversed by good oral hygiene and professional dental cleanings at our East Lyme, CT office. Acids responsible for tooth decay come from the wastes of mutans streptococci and lactobacilli bacteria that thrive in dental plaque, a substance that is the leading cause of periodontitis.

Where do demineralizing acids come from?

Dietary sugars comprise the bulk of tooth-decaying acids, including table sugar, cooked starches, fructose, glucose, and lactose. In fact, as soon as you bite down on a sugary cookie or into a French fry, bacteria start digesting sugars, breaking them down and eventually excreting them as demineralizing acids. As this bacteria colony grows and becomes organized, plaque develops and forms that tough, yellowish coating you often see on the tops of teeth at the gumline.

Plaque is the Problem

Dental plaque is a filmy type of nesting place for bacteria that also keeps acids pressed against tooth enamel. Since plaque cannot be removed by brushing, it is important that a person who suffers tooth decay visit Robson Dentistry immediately so we can use special tools to scrape and thoroughly clean teeth.

Signs of Tooth Decay

Early tooth decay and cavities remain asymptomatic until demineralization creates a hole deep enough to reach the tooth’s inner tissues and nerve endings. Eventually, tooth decay will cause tooth sensitivity, toothache, vague pain when biting down on the affected tooth, and possibly pus seeping around a tooth’s gum line if the decay creates an infection. If treatment is delayed long enough, a decaying tooth may loosen, crumble, and ultimately fall out, which leaves an empty or partially empty socket.

Preventing Tooth Decay

Getting regular checkups with Dr. James Robson, brushing and flossing twice a day, and eating fruits or crunchy vegetables at snack time instead of a candy bar or doughnut are the three best ways to keep your teeth healthy, white, and where they should be: in your mouth.

Dr. James Robson and our team at Robson Dentistry hear this question all the time. Millions of people have dental crowns that artificially restore the chewing surface of a tooth. Also known as caps, these restorations surround the entire portion of the tooth that is above the gum line. Crowns are custom fabricated to match the color, shape, and size of other teeth and are visually undetectable to others. Several types of materials can be used to create crowns, including stainless steel, resin, metal alloys, porcelain fused to metal, or ceramic. When properly cared for and accurately fit, crowns can stay in place for a decade or more.

There are many reasons to get a dental crown, including:

• To restore a broken or cracked tooth
• To protect a tooth after a root canal
• To restore a severely decayed tooth
• To help anchor a dental bridge
• To complete a dental implant
• To protect a tooth that is at high risk for developing decay
• For cosmetic purposes

Getting a dental crown

The process of getting a dental crown begins at our East Lyme, CT office. X-rays are used to ensure the teeth are healthy enough to receive a crown. If the roots and surrounding bone are in satisfactory condition, the tooth will be numbed, filed, and reshaped in preparation for the crown. If the tooth root is not healthy, a root canal may be necessary first.

After the tooth is prepared, a special paste is placed over the upper and lower teeth to make impressions. These impressions serve as blueprints for the dental laboratory responsible for making the crown. They also help ensure the position of the new crown will not negatively affect a patient’s bite. The prepared tooth is protected by a temporary crown while the permanent one is made. When ready, the permanent crown replaces the temporary crown and is cemented in place.

Gum disease, also called periodontal disease, is an infection of the gum tissues, and is something seen all too often by Dr. James Robson. Extending from inflammation of the gums (gingivitis) to more serious infections and complications (periodontitis), there is a wide range of gum disease severity.

Not only does gum disease affect the health of your mouth and teeth, but according to the National Institute of Dental and Craniofacial Research, it can affect your general health as well. This is because an infection in the mouth as a result of gum disease can travel to other parts of your body through the bloodstream. Gum disease is also a risk factor for heart disease, and can play a role in blood sugar levels.

Causes and Risk Factors

Gum disease is essentially caused by the build-up of bacteria in your mouth. If you brush and floss every day, this bacteria is washed away, but if not, it turns into plaque. If left unchecked, this plaque buildup can lead to gum disease.

Some of the common risk factors for gum disease include not taking good care of your teeth, failing to have one’s teeth cleaned every six months, experiencing hormonal changes, smoking cigarettes, developing diabetes, being genetically exposed to gum disease, or taking certain types of medications.

Gingivitis versus Periodontitis

There are two main types of gum disease: gingivitis and periodontitis. Both are bad for you, but gingivitis is less severe. It is typically the first stage, and involves inflammation of the gums from plaque and tartar on the teeth. If your gums are swollen and bleed, this is a sign of gingivitis.

Periodontitis, a more severe case of gum disease, occurs when your gums pull away from the teeth and pockets form. These pockets are a concern because they can harbor infection.

Treatments for Gum Disease

Treatments for gum disease depend on the cause and severity. Deep cleaning to remove the plaque underneath the gum line – called root scaling and planing – is one of the most common treatments for gum disease. Antibiotics placed under the gums to rid you of an infection or reduce the inflammation may also be advised. In some cases, surgical procedures, including flap surgery and bone and tissue grafts, are needed.

If you have bleeding or swollen gums, pockets between your gums and teeth, pain, or other issues, you might have gum disease. Visit Robson Dentistry for an exam and learn the best course of action.
