When should a filling be replaced?

September 28th, 2022

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. Tenney.

Five Common Reasons for Emergency Care Visits

September 21st, 2022

A dental emergency can strike anywhere, anytime, and without warning. Perhaps you’re playing a game of touch football on Thanksgiving and your brother-in-law decides to up the ante and tackles you, accidentally knocking out your two front teeth. Or maybe you’re on vacation somewhere in the tropics and decide to go deep-sea fishing, but when you’re climbing onto the boat you slip on the dock, fall, and chip three of your teeth. From misplaced fly balls to bagel seeds causing a painful bout of inflammation, there are all kinds of dental emergencies.

Here are the five most common reasons for emergency care visits.

  1. Somehow you've managed to knock out a tooth. Whether it's the result of a sports injury or because of decay, when you lose a tooth, you need emergency dental care. If the tooth is salvageable, then it can be reattached to the socket, but this needs to be done within a one- or two-hour window.
  2. A chipped tooth is the most common dental emergency. Small chips can be caused by food (chicken bones and nuts have sent many people to the dentist); however, it's usually some sort of accident or injury that more often causes a chip. While you might be embarrassed to walk around with a gaping chip in your front tooth, it is easily fixed with a bond, crown, or veneer.
  3. A broken tooth is more severe than a chipped tooth. When a tooth breaks, it might be due to a small or hidden chip. However, chances are the pain and discomfort will be more severe.
  4. It might seem comical, but getting a piece of food lodged in the wrong place can result in a dental emergency. If something gets stuck deep in a crevice, it can cause pain and inflammation.
  5. The loss of a filling happens more often than you think. When you lose a filling, you need to receive emergency care immediately. If you don’t, you risk further damage to your tooth.

When you injure your teeth or mouth, you need to seek emergency care as soon as possible. In the event of a suspected emergency, don't wait. Contact Dr. Tenney immediately.

Tips for a Whiter Smile

September 14th, 2022

Everyday life can take a toll on the whiteness of our teeth: Foods we love as well as soft drinks and coffee can stain them over time. Poor brushing and flossing can also leave behind tooth stains. Even injuries to teeth or gums can cause some yellowing, and in certain cases, medicines can contribute to discoloration.

So don’t get discouraged if you notice your smile has dimmed. You can definitely take action to restore the natural beauty of your teeth. Here are some of the best ways to whiten them:

  1. Drink through a straw or cut back on coffee and soft drinks to reduce risk of stains.
  2. Brush and floss every day.
  3. Try a whitening toothpaste or mouthwash.
  4. Visit our Glendale office every six months for regular cleanings.

We also offer in-office professional whitening at our Glendale office. These whitening products are much more effective than whiteners you can buy at the store and are completely safe. Since they’re stronger, application by a member of our team is essential to achieve the best results.

Still, some teeth can resist bleaching. If that’s the case, we can try several other techniques, such as deep bleaching that applies whitening agents over several visits, veneers and bonds that cover existing stains with a whiter, brighter surface, or laser whitening.

If a whitening session is something you’d like to pursue, be careful about whom you trust to perform the procedure. Avoid using “bleaching stations” in shopping malls or at fairs. These so-called whitening techniques can irritate your teeth and gums, and leave them highly sensitive to pain.

Also, operators of these whitening stands will make customers apply the bleach themselves, to avoid charges of practicing without a license. That should serve as a red flag and a caution to seek trained professionals like Dr. Tenney, instead.

Back to School? Remember Your Dental Homework!

September 7th, 2022

It’s a busy time of year. Book lists! Supplies! New clothes! (How did they outgrow those shoes already?) And while you’re preparing your family’s list of back-to-school necessities, here are a few essential reminders to help your child begin the school year with a healthy smile.

  • Review

It never hurts to review the basics before the start of the school year, and that holds true for dental care as well! Make sure your child is brushing two minutes twice a day, and using floss or another interdental tool to clean between the teeth. If his toothbrush has been in use since the end of the last school year, it’s probably time to replace it. Bristles are at their best for about three months—after that, they become frayed and worn, and can’t remove plaque as effectively.

  • School Supplies for Braces Wearers

If your child is going to school with braces for the first time, send her off with the tools she needs. A travel-sized toothbrush and tube of toothpaste are perfect for a quick brushing after lunch, while dental floss and a threader or dental picks will take care of any after-lunch particles lurking in brackets and wires. Orthodontic wax is a great product to have on hand if a wire or bracket is causing irritation. If your child uses clear aligners or a retainer, make sure a protective case is always close by, ready to use every time the appliance is removed. And it’s a good idea to include the number of your dentist and orthodontist in her contacts in case of emergency.

  • Exams

If your school requires a dental exam before the start of classes, be sure to make your appointment at our Glendale office now! Regular checkups with Dr. Tenney are vital for preventing small problems from becoming bigger ones, and a professional cleaning will remove the plaque even careful brushing can miss.

A positive, confident start can set the tone for the academic year, so your homework might include monitoring summer reading, providing required supplies, and making sure your child is well-rested and ready to go. You can also help your child to a positive, confident start by monitoring brushing habits, providing the necessary tools for appliance-wearers, and making sure your child is up-to-date with dental exams and cleanings. Because entering the classroom with a beaming, healthy smile—that’s an A+ way to begin the school year!
