When should a filling be replaced?

June 17th, 2026

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 John Pappas.

Are dental X-rays safe?

June 10th, 2026

YES! X-rays have been used in dentistry for a long time, and the amount of radiation has significantly decreased with advances in technology. While there is risk in every health diagnostic procedure at Masterpiece Dentistry at Copley, the benefits must outweigh the risks. Dental X-rays do indeed fall into this category.

X-rays are exposed to a type of film to produce an image. The amount of X-rays required to produce this image differs with film speeds. Speed E or F is highly recommended, and digital X-rays require up to 50% less than speed E or F film. The digital X-ray software can adjust the exposure to produce a quality image. Digital X-rays are becoming a new standard and are most common.

Lead aprons have been used to reduce the amount of scatter radiation. All X-ray units have a cone to focus the X-ray beam so the exposure is highly localized. Lead aprons continue to be worn as a precaution for pregnant women, and a thyroid collar should also be worn. In most cases, this is sewn into the lead apron.

We get radiation exposure from environmental factors as well as healthcare diagnostic and treatment tools. To place this in perspective, in one year a person is expected to have 360mRem per year from the sun, air etc. By comparison, a single set of bitewing X-rays is 0.3mRem. Radiation can accumulate in our body over a lifetime, and additional exposure should be avoided whenever possible.

Warming Up for Summer Weather

June 3rd, 2026

The barbecue’s fired up. T-shirts and shorts are back in style. Sandy beaches and sidewalks are sizzling. Summer’s officially here, and it’s time to get back into hot weather mode. This means getting back into some healthy summer habits.

Be Ready to Hydrate!

Warm weather can lead to dehydration before you know it. And water does more than hydrate—it rinses away food particles after eating or snacking, neutralizes enamel-eroding acids in the mouth, and helps us keep up healthy levels of saliva. 

  • A reusable water bottle is a summer shopping list must. When you’re out walking, hiking, exercising, or camping, you can’t always be sure you’ll have fresh water available. Fill your water bottle before you leave home—you’ll help yourself stay hydrated, save money, and protect the environment, too!
  • Go light on the sports drinks and sodas when planning your summer menus. They’re often filled with sugars and acids—two very unhealthy ingredients for your teeth. 

Restock Your Sunscreen

Sunscreen helps protect skin of all shades and all ages. Exposure to ultraviolet rays is known to cause skin cancer and premature aging. Lip tissue is thin and delicate, especially at risk from the sun’s damaging UV rays. 

  • Check your sunscreen for its expiration date. Protective sunscreens and lip balms lose effectiveness once that date has passed.
  • Some sunscreens are designed for use on lips. If yours isn’t, look for a protective lip balm. All of your sunscreens and balms should have an SPF (Sun Protection Factor) of 30 or higher.
  • Bring your sunscreen and balm with you when you’re out and about, and reapply every two hours, or sooner if you’re eating, drinking, or getting wet.

Prep for Summer Adventures

If you’re travelling this summer, make sure the right dental supplies are part of your gear. A travel size toothbrush and toothpaste, a well-ventilated toothbrush case, dental floss, and your dentist’s emergency contact information are basic necessities. Once you have the basics, you can tailor your kit to your summer plans:

  • Flying? Make sure every liquid, gel, or aerosol you’ll need is the proper size for carry-on flight rules, 3.4 oz (100 ml) or less. Toothpaste and mouthwash are included in these categories, so look for travel sizes in your favorites. 
  • Going overseas? Don’t forget plug adaptors or voltage converters if needed for your electric toothbrush.
  • Camping? An emergency kit with cotton rolls, over-the counter pain relief, oral pain relief gel, dental wax (for damaged braces or a broken tooth), and even temporary fillings and a tooth preservation kit can be crucial in case of unexpected dental injuries.

Make Sure Dental Care Is on Your Summer Calendar

Laid-back summer days are the best, but laid-back dental care really isn’t! Follow your healthy dental routine even during the lazy days of summer.

  • Keep up with your brushing and flossing—brush two minutes twice each day with a fluoride toothpaste, and floss at least once a day.
  • If you’re planning a trip, don’t ignore warning signs. If you have tooth pain or sensitivity, see your dentist to treat any problems before you’re cruising at 30,000 feet or enjoying a remote campout miles from anywhere.
  • Make sure you keep up with your scheduled exams and cleanings. That’s the best way to ensure year-round dental health!

Whether you’re basking in the warm outdoor weather, relaxing in the shade with a cool drink and a good book, on the road to adventure, or wherever your summer plans take you, we hope these easy tips will help you create a summer filled with bright, healthy smiles.

I have fluoride toothpaste and fluoridated water; do I need a fluoride treatment?

May 27th, 2026

Fluoride is a naturally found ion with a history of greatly reducing the incidence of tooth decay in children. However, over the past decade, people have increasingly consumed bottled water, most of which does not contain fluoride, and children are no longer getting the recommended dosage of fluoride. In addition, many areas do not add the optimum amount of fluoride to the town drinking water.

Everyone’s dental needs are different. The amount of fluoride a person needs is determined by age (children), tooth sensitivity, risk for cavities, and medical conditions. When a patient needs additional fluoride it can be applied in a foam or varnish.

Children receive additional topical fluoride because teeth in the early development stages have a higher mineral uptake. The future strength of the enamel depends on this. When a tooth absorbs the fluoride ion, it creates hydroxyapatite, a harder mineral compound than enamel alone.

Those who have a dry mouth from medication also need extra fluoride. A daily fluoride rinse and a semi-annual fluoride varnish treatment are standard. If you are on medicine for high blood pressure, anxiety, diabetes, depression, or cholesterol, you may fit in this category.

Cancer treatments can also greatly impact your oral health. Fluoride varnish treatments prior to, during, and after radiation and chemotherapy can be beneficial. There are other mouth conditions which coincide with cancer treatments which make it difficult to brush and floss daily, and can contribute to an increased risk for decay. An infection during cancer treatment can be especially harmful, which is why preventive measures are important.

Fluoride treatments, administered topically, are highly beneficial in preventing decay. Feel free to call Masterpiece Dentistry at Copley to schedule an appointment or if you have any questions.
