What causes stains on teeth?
Staining can occur on the outside surfaces of teeth and is caused by foods such as red wine, coffee, and tea, as well as by tobacco use. They can also be developmental, affecting the structure of the teeth due to excessive fluoride levels or from tetracycline antibiotics given during childhood to name a few. Changes in a tooth's enamel or dentin during tooth formation, or as teeth age, can also cause discoloration.
What is going on inside a tooth's structure that makes it look stained?
Most of a tooth's covering (95 percent) is composed of highly mineralized enamel. The crystals of enamel are contained in a framework, or matrix, of organic matter. Dentists believe that various organic compounds that get into this matrix can cause staining.
How do whiteners work?
Tooth whiteners or bleaches expose the teeth to a peroxide compound. This creates reactive oxygen that breaks down highly colored organic compounds within the tooth's sub-surface matrix, making the tooth look whiter, but without changing its internal structure.
What professional in-office whitening techniques are available?
During treatment, a high concentration of peroxide solution in the form of a gel is applied directly on the teeth, often with activation by a heat or light source. These systems use custom tailored trays fitted to an individual's mouth. Silicone barriers or protective gels are used to keep the peroxide gel away from the gums or sensitive membranes in the mouth.
How are professional home whiteners different?
Home whiteners involve a less concentrated solution of peroxide in a gel form. It is delivered to the tooth surface by a bleaching tray that is custom-made in your dentist's office. Over-the-counter whiteners such as whitening strips or paint-on formulas can also be used, but they take longer and they're not as effective — the more diluted solutions are used for safety.
Can toothpastes really whiten teeth?
Mild abrasives in toothpastes clean surface stains but cannot change the underlying tooth color or remove significant staining.
How long do the results last?
Usually, the results last from six months to two years, but effects will diminish over time. You can make them last longer by avoiding the foods and habits that cause staining.
Are teeth whiteners safe to use?
Teeth whitening products are safe if used according to our recommendations or the product manufacturer's directions. Peroxide products may be toxic if used in excess of recommended intervals and amounts.
Tooth pain occurs when a trauma or infection triggers a reaction from the nerves inside a tooth's pulp chamber. The severity of the pain and its duration can vary depending on the underlying cause, which can include anything from a loose filling to an abscess. Ignoring symptoms not only results in unnecessary physical and emotional pain, but can also lead to more expensive dental treatment as problems become more complex. Make an appointment with our office today if you are experiencing any of the following symptoms:
- Sharp pain when biting down on food — This type of pain could be indicative of a cracked tooth, loose filling, or tooth decay that is affecting one or more of your teeth. We can remove decay and replace a loose filling, but if your tooth is cracked, we will have to determine the location and depth of the crack before formulating a treatment plan. In some cases, root canal treatment or even extraction may be necessary.
- Pain that lingers after eating hot or cold foods or liquids — Mild and short-term sensitivity (lasting only seconds or a minute) to hot and cold foods resulting from gum recession can often be soothed by using a fluoride toothpaste made for sensitive teeth. However, an inflamed tooth pulp or one that is dying due to severe decay could cause sensitivity that lingers for a long time after exposure. In this case, root canal treatment may be necessary to remove dying pulp tissue in order to save the tooth.
- Constant severe pain and pressure, swelling of the gums, and sensitivity to touch — Infections and/or abscesses can spread from the tooth pulp into the surrounding periodontal tissues and bone causing this type of pain. Root canal treatment will most likely be required.
- Dull ache and pressure on one or both sides of the face in the upper teeth region — The sinuses and upper back teeth share the same nerves, so, oftentimes, referred pain from sinus congestion or infection can feel like a toothache. A thorough examination can determine whether or not the pain is dentally related.
If you are experiencing tooth pain, call our office immediately so that we can begin to provide you with some relief. To read about other symptoms of tooth pain and possible treatment options, read the Dear Doctor magazine article “Tooth Pain? Don't Wait!”
Dental implants are in much demand when it comes to replacing missing teeth. And although they have long-term success rates of well over 95% when properly placed, the dental profession's current rule-of-thumb is to not use them as a treatment option for teenagers because jaw and facial growth are not complete.
As with most things in life, timing can be everything. However, having missing teeth as a teen can contribute to significant loss of self-esteem and psychological issues. All this means is that we must review each patient's needs on a case-by-case basis so that we can determine the optimal time to place implants while maintaining your teen's self-esteem. However, the good news is that there are some temporary tooth replacements available until the timing is right for implants.
Unlike natural teeth, which move and change position along with normal growth and jaw development, implants don't. Because implants replace tooth roots by fusing with the jawbone, their position is fixed. If placed before normal jaw growth and maturity are complete, they appear to sink as the jaws grow and leave them behind!
Given the above details, you can clearly see why it is critical for jaw and facial growth to be complete prior to placing a dental implant. To determine this timeline, we will work with our dental team, which include orthodontists (specialist in the study of the growth, development and moving teeth into the right positions). Working together, we will best be able to assess when the time is right to plan and place dental implants — usually around late teens.
