Alleviate Tooth Sensitivity

July 30th, 2014

If a sip of ice water, spoonful of ice cream, or piping hot latte is enough to send shivers up your spine from tooth sensitivity, be assured you are not alone. It’s estimated that as many as one in eight adults suffers from tooth sensitivity.

What causes sensitive teeth?

Some of the causes of tooth sensitivity include brushing too hard, a cracked tooth, receding gums, periodontal disease, tooth bleaching, or other conditions that expose the sensitive roots of your teeth. For example, brushing too aggressively can injure your gums, and lead to exposed roots and tooth sensitivity.

When the enamel on the outside of the tooth or tissue located between the teeth breaks down or wears away, nerves inside the tooth trigger sensitive teeth that are particularly noticeable when you drink or eat anything hot or cold.

How to alleviate tooth sensitivity

Fortunately, there are a number of things you can do, both at home and at the dental office, to reduce the discomfort of sensitive teeth. Brushing with desensitizing toothpaste is one of the ways to reduce tooth sensitivity: it works well for many patients, and is typically the first course of action.

  • Brush with toothpaste specifically designed for sensitive teeth.
  • Change the way you brush by using a soft toothbrush and not brushing too aggressively.
  • Avoid brushing teeth after consuming acidic foods and beverages, like orange juice and pickles.
  • Drink water or milk after eating or drinking acidic foods or beverages.
  • Sip through a straw when you drink acidic beverages.
  • Wear a mouthguard at night to prevent teeth grinding that wears down teeth.
  • Ask Dr. Keldsen about fluoride dental treatments or plastic resin.

For moderate-to-serious cases of tooth sensitivity, more invasive professional dental treatments are available. These include a bonding agent designed to seal/cover the exposed root, obtaining new gum tissue through graft (for receding gums), fillings, crowns, inlays, or bonding. When tooth sensitivity is persistent and results in hypersensitivity, endodontic treatment in the form of root canal may be recommended.

What exactly is a root canal?

July 23rd, 2014

Hearing that you need a root canal can be highly intimidating. What is a root canal? It is the removal of the nerve supply from the tooth. Here, Dr. Keldsen will describe the parts of a tooth and explain the reasons for a root canal and how it is done when you visit us in our Bend, OR office.

Your tooth is made up of many layers. The outside layer is called enamel and is made of minerals. The middle layer is dentin, which is also a calcified tissue, but less dense. The center of the tooth is called the pulp, and that hosts the nerves and blood vessels. A root canal is the removal and replacement of this center with a sterile filling.

A root canal is needed when an infection spreads to the center of the tooth. This can be from trauma (recent or previous), a cavity, a severe crack, or other compromise that causes nerve damage. An X-ray and examination are required to see if a root canal is needed. Symptoms may include but are not limited to pain, swelling, change in tooth color, and over-reaction to temperature change or pressure.

When it is time to begin, you’ll receive local anesthesia (via injection) to make you most comfortable. A rubber dam is used to isolate the tooth, while other equipment determines the nerve location and maintains a sterile working environment. All of the infected area is removed including the nerve tissue and blood vessels. Then, medicines are used to sterilize and alleviate any pain. Next is the placement of a filling material in the spot where the nerve used to be.

When your nerve and blood supply are taken away, the tooth is non-vital, or dead, and can become weak and fragile. If your tooth is badly decayed, a large portion of it will have to be removed. It is recommended to place a crown on the tooth to keep the enamel from breaking or falling apart. If you do not get a crown, you could eventually lose the tooth to more decay or infection. The tooth could also break off completely and you would have to have an extraction. The crown fits over the top of the tooth and secures it from breaking down.

A root canal saves the life of a tooth that would otherwise succumb to further infection and eventually extraction. Infection is the cause of most-needed root canals. If you are ever unsure what is happening at your appointment, don’t be afraid to ask questions so you understand the procedure completely.

Is dairy crucial to my child's oral health?

July 16th, 2014

Healthy eating, combined with regular physical activity, plays a vital role in your child’s health and well-being. Dairy foods are naturally nutritious, packed with ten essential nutrients that help your child feel good for life. But did you know that dairy is also great for your child’s dental health? Our team at Keldsen Family Dental Care will tell you that, in addition to providing large amounts of much-needed calcium, dairy products also help fight cavities! Dairy products have a specific role to play in dental health as they contain a unique combination of special anti-decay nutrients such as calcium, phosphorus, and the protein, casein. Cheese is especially useful, as eating a small piece of cheese after consuming sugary foods or drinks can help protect teeth and reduce the risk of tooth decay.

If you’d like to know more about the importance of dairy products in your child’s diet, or about any aspect of your child’s dental health, feel free to ask Dr. Keldsen at your next appointment!

What are dental implants?

July 9th, 2014

Do you have a space where a tooth used to be? Were you born with a missing tooth? Are you getting ready for dentures? You may be a good candidate for a dental implant. Metal dental implants were invented in 1965. Technology continues to advance with millions of implants placed in the United States and Canada. Placing implants has become mainstream and a common practice for offices like ours.

A dental implant is a small titanium post, which resembles a screw with threads. The post also has holes for bone to integrate. A dental implant is placed into the jawbone during a short dental procedure. It is relatively painless with very little post-operative pain. The threads on the implant post allow for the bone to fill in and integrate. To facilitate this process the implant is re-covered with gum tissue and allowed to heal and integrate for nearly three months. The implant acts as the root for the tooth to provide solid and stable support for the crown that’s yet to be placed.

The next step in the dental procedure is to uncover the implant and place a healing cap to allow the gum tissue to heal. After a short period of healing, an impression is taken to fabricate a crown to fully restore the missing tooth. The crown is then cemented on top of the post, at which point you can resume normal eating activities.

Dental implants do require some special care, but that is easily managed when you follow the directions outlined by Dr. Keldsen. During your regularly scheduled cleaning, special instruments are used to clean implants. While a dental implant cannot get a cavity, a condition known as peri-implantitis can occur. This is very similar to periodontal disease as the end result is dental implant loss and loss of bone structure. Be sure to floss the dental implant daily and run the floss under the implant crown as far as it can go to remove food and plaque. If you use any picks or small brushes to go in between your teeth, make sure they are plastic. Metal will scratch the implant making it more susceptible to infection. Be sure to keep your regular dental visits and cleanings to monitor the implant and help preserve your investment.
