Long ago dental work could be painful and stressful—often for both patient and practitioner. Thankfully, that time is long past: today, most procedures are painless in large part due to local anesthesia.
Local anesthetics are numbing substances applied to specific areas of the body like the teeth and gums to temporarily block pain during a procedure. And because they only affect a localized area of the body, you remain conscious and alert throughout the procedure.
To achieve the level of numbing necessary for dental work, we often need to deaden the gums using a needle to deliver the anesthetic. But then this poses a secondary pain concern—the needle stick itself.
Again, topical anesthesia comes to the rescue in the form of a swab, patch or spray applying an anesthetic directly to the top layer of the gums at the injection site. This numbs the area and prevents you from feeling the needle stick. It's highly probable, therefore, that from start to finish you won't feel any discomfort during your dental work except perhaps for a little pressure.
Local anesthesia truly is a game changer for dental care—and not just for the patient. A dentist who's concerned about their patient's comfort level may work hurriedly to complete a procedure. But if their patient is relaxed, the dentist can work calmly and methodically. The result is better, more focused care.
For all its improvements in the patient experience, though, there has been one consistent complaint—the numbness that often lingers for a while after the procedure is over. But there have been advances in recent years that have helped reduce this irritation: new anesthetic agents (even some that can reverse the anesthetic effect) and fine-tuned dosages can help keep residual numbing to a minimum.
Not all procedures like routine teeth cleanings or enamel shaping require anesthesia. But when it's appropriate, local anesthesia can make your next dental visit much more pleasant.

Everyone knows that in the game of football, quarterbacks are looked up to as team leaders. That's why we're so pleased to see some NFL QB's setting great examples of… wait for it… excellent oral hygiene.
First, at the 2016 season opener against the Broncos, Cam Newton of the Carolina Panthers was spotted on the bench; in his hands was a strand of dental floss. In between plays, the 2105 MVP was observed giving his hard-to-reach tooth surfaces a good cleaning with the floss.
Later, Buffalo Bills QB Tyrod Taylor was seen on the sideline of a game against the 49ers — with a bottle of mouthwash. Taylor took a swig, swished it around his mouth for a minute, and spit it out. Was he trying to make his breath fresher in the huddle when he called out plays?
Maybe… but in fact, a good mouthrinse can be much more than a short-lived breath freshener.
Cosmetic rinses can leave your breath with a minty taste or pleasant smell — but the sensation is only temporary. And while there's nothing wrong with having good-smelling breath, using a cosmetic mouthwash doesn't improve your oral hygiene — in fact, it can actually mask odors that may indicate a problem, such as tooth decay or gum disease.
Using a therapeutic mouthrinse, however, can actually enhance your oral health. Many commonly available therapeutic rinses contain anti-cariogenic (cavity-fighting) ingredients, such as fluoride; these can help prevent tooth decay and cavity formation by strengthening tooth enamel. Others contain antibacterial ingredients; these can help control the harmful oral bacteria found in plaque — the sticky film that can build up on your teeth in between cleanings. Some antibacterial mouthrinses are available over-the-counter, while others are prescription-only. When used along with brushing and flossing, they can reduce gum disease (gingivitis) and promote good oral health.
So why did Taylor rinse? His coach Rex Ryan later explained that he was cleaning out his mouth after a hard hit, which may have caused some bleeding. Ryan also noted, “He [Taylor] does have the best smelling breath in the league for any quarterback.” The coach didn't explain how he knows that — but never mind. The takeaway is that a cosmetic rinse may be OK for a quick fix — but when it comes to good oral hygiene, using a therapeutic mouthrinse as a part of your daily routine (along with flossing and brushing) can really step up your game.
With all the new tooth-colored fillings for cavities, it's easy to overlook metal amalgam. While this mainstay of dental care for over a century might not be as attractive as composite resins or glass and resin ionomers, it still has the advantage of strength and durability.
Amalgam is a stable metal alloy usually made up of silver, tin, copper and mercury. The metals are proportioned and mixed precisely to guard against “free” mercury molecules, which could pose a health hazard. The mixture is pliable at first, but then sets hard once molded into the prepared area of the tooth.
Besides strength, amalgam's other advantages include low cost, high resistance to wear and biocompatibility (not toxic to the body or allergy-producing). At the same time, it can require more tooth structure removal to accommodate a filling and cause higher sensitivity to temperature for a while after installation. Its main disadvantage, however, is appearance — it's now considered unacceptable from an aesthetic point of view to use it in visible areas like the front teeth.
Because of this, materials resembling natural tooth color are coming into vogue, especially as their strength improves. Still, dental amalgam continues to play a useful role, especially in less visible back teeth with higher chewing forces.
One past concern about dental amalgam is the inclusion of mercury in the alloy. As mentioned before, mercury is hazardous in a “free” form when not knit microscopically with other metals; as such it can emit a vapor that could enter the bloodstream and damage the nervous system. But after several studies by various organizations, the American Dental Association has concluded amalgam's precise mixture prevents the mercury from taking this form: although some vapor is given off during chewing it's far too low in concentration to pose any danger.
Dental amalgam continues to be an effective choice for fillings. Whether it's the right choice for you will depend on the type and location of a tooth to be filled, and whether durability is a higher concern than appearance. If we do recommend an amalgam filling, you can be assured it's a safe and lasting choice.

One of the top concerns in public health today is exposure to the metallic element mercury within the environment. At abnormal levels, mercury can have a toxic effect on our nervous systems and cause other health problems.
These concerns over mercury have also increased attention on one material in dentistry that has included the metal in its makeup for over a century — dental amalgam for filling teeth. Amalgam is a metal alloy that can include, in addition to mercury, silver, tin, and copper. When first mixed dental amalgam is a moldable material used for fillings in prepared teeth. It then hardens into a durable restoration that can withstand biting forces.
While the use of amalgam has declined with the introduction of life-like colored fillings, it's still used for teeth like molars subject to high biting forces. With what we now know about the ill effects of mercury (which can make up to half of an amalgam mixture) is it safe to continue its use?
The American Dental Association has performed extensive research into amalgam safety. They've found that mercury is stabilized by the other metals in the amalgam. This prevents "free" molecules of mercury, the real source of harm to health, from escaping into the blood stream in the form of vapor. Although trace amounts of mercury vapor from the amalgam are released as a person chews, those levels are well below the threshold that could cause harm.
From a patient standpoint, the biggest drawback to dental amalgam isn't safety — it's the appearance of teeth it's used on. Silver fillings aren't considered attractive. And now there are viable filling alternatives that not only look like natural teeth but can withstand biting forces almost as well as amalgam. These materials include composite resins, mixtures of glass or quartz within resin, or glass and resin ionomers. Each of these has advantages and disadvantages depending on how and where they're applied.
After a thorough dental examination, we'll be able to advise you on what filling material will work best to produce the best result. And if we do suggest dental amalgam you can rest assured it will be a safe choice.

Ever wonder just exactly what causes cavities? Once upon a time, “Toothworms” — miniscule, yet relentless pests — were thought to be responsible for this widespread malady. This belief persisted from ancient times through the 17th Century; William Shakespeare even made reference to the baneful beasts in his play Much Ado about Nothing. (“What, sigh for a toothache? [It] is but a humor or a worm.”) Today, however, we know why no one ever observed an honest-to-goodness toothworm: it’s because they’re much too tiny to see with the naked eye.
Actually, it isn’t worms, but much smaller organisms that cause tooth decay. These harmful plaque bacteria (along with many helpful microorganisms) live in the mouth, and build up on surfaces of the teeth when they aren’t cleaned properly. They feed on sugar in the diet, and release substances that erode tooth enamel, which causes small holes called cavities. Cavities, in turn, are what’s responsible for most toothaches.
While we may scoff at old legends, one fact remains: Even today, according to the National Institutes of Health, tooth decay is the number one chronic disease of both children and adults; and it’s almost entirely preventable. We can’t blame it on toothworms — but what can we do about it?
Glad you asked! The best way to avoid decay is through prevention. That means brushing your teeth twice a day with a fluoride toothpaste, and flossing them every day. It also means eating a balanced diet and avoiding acidic and sugary foods — like soda, some juices, and sweet, sticky snacks. If you do consume these types of foods, limit them to mealtimes; that gives your saliva enough time in between to neutralize the acids naturally. And, of course, make an appointment see us twice a year for a complete check-up and professional cleaning.
If you do begin to notice the symptoms of tooth decay (toothache, for example) it’s important to come in to the dental office right away, so we can treat the problem before it gets worse. Prompt action can often help save a tooth that might otherwise be lost. Besides filling the cavity, we may be also able to recommend ways to help prevent the disease from affecting other teeth. And if you need a more extensive procedure to relieve the problem — such as a root canal — we can make sure you get the appropriate treatment.
We’ve come a long way since the “toothworm” days — but we can still do a lot more to make tooth decay a thing of the past.
