LASERS ARE THE FUTURE
I bought my first dental laser in 2008. I thought it was the coolest thing to be able to reshape gums with it or cut away a growth for a biopsy.
I have since purchased several other lasers. Each laser offers a different wavelength guided by a sophisticated computer to enable different procedures. Some lasers are best for cutting soft tissues such as gums, cheeks, and tongue. Other lasers are best for working on hard tissues such as teeth and bone. There are a few lasers that can cut both types of tissues, but remain cost prohibitive for most general use applications(more than $120,000 initially plus ongoing costs). There is also photobiomodulation – a technique of using low level light energy (cold laser) that does not cut at all, but is used to stimulate faster healing in the body.
WHY USE LASERS?
Lasers slowly cut away diseased tissue in a way that triggers less inflammatory response from the body than scalpel or drill. Lasers sterilize the area because they destroy good and bad cells alike as they cut, thus bacteria and viruses are destroyed in the process. The power and effectiveness of harnessing different light energies is truly amazing. Scientists are still researching the best wavelengths and power outputs for numerous applications.
Not yet…We recently used a very high end laser in our office for 9 months. While the manufacturer claimed there was no need for anesthetic, our experience was that this was true for only about half of the patients. The other half of patients very much would have appreciated numbing first. We deemed this to be not good enough and have discontinued its use without anesthetic. We want our patients to be able to relax and not worry that they will feel pain midway through a procedure.
Lasers should eventually replace the drill and scalpel for most if not all dental procedures, however, the cost of this technology needs to come down considerably before it can see widespread adoption. We will continue to keep a close eye on the laser market and adopt the technologies that make the most sense for our patients’ welfare.

Wisdom Teeth – Should they stay or should they go?
by Michael E. Bass, DDS, FAGD
What should you do about your 3rd molars (wisdom teeth)? Nearly every teenager and adult has to face this question at some point. The quick answer is that as soon as they are developed enough to remove, then get them removed (typically some time between age 16 and 20). Each year you wait beyond that, you increase the chances of collateral damage. Once you reach your 30’s and beyond, you now have to weigh the pros and cons much more closely as you just don’t heal as well as you once did.
Why do we even have wisdom teeth?
Anthropologists who have studied this have given some interesting insights. Thousands of years ago, our diet was much more coarse and so teeth would not only wear down on the tops, but in between the teeth as well. This would have created more space in the mouth for all the teeth to fit. Also, life spans were shorter and so some of the end stage diseases (like periodontal disease) that we see with wisdom teeth now may not have happened because people didn’t live long enough. Finally, over the years there has been more scrambling of the genetic code as small people with smaller teeth and jaws marry bigger people with bigger teeth and jaws, you begin to get more variability and randomness in the amount of space people have available for the size of teeth in their mouths.
How do you know if you can keep your wisdom teeth?
Let’s be clear – very few people these days will benefit from keeping them. The ironic thing is that while you are young and healthy, your wisdom teeth may not bother you at all and so you assume that all is well. It is not until you are much older that you realize problems are developing, but, by then you may be past the time in life where you will heal as quickly and uneventfully. A dentist will take a panoramic x-ray that will show the wisdom teeth, what angle they are coming in, and how developed they are. Many of the wisdom teeth do have enough room to come, but they don’t have enough room to have the type of gums around them (keratinized gingiva) that will create a good long term seal around the backs of them. It is more like your cheek tissue is running right up against the back of the tooth. This will eventually be the weak link where gum disease and bone loss begins. Other wisdom teeth may be at an angle where they won’t be able to come in all the way (impacted). These can cause damage to the back side of your good molars (2nd molars) that you do want to keep.
In my 20 years of experience in dentistry, I have seen that people usually aren’t able to keep their wisdom healthy enough even if they do have enough room for them to come in because they are so far in the back of the mouth. They don’t get brushed and flossed well enough and
food lingers back there causing cavities and gum problems. Most of your chewing takes place in front of these teeth. Studies have shown that less than 2% of adults with wisdom teeth at age 65 and beyond are able to maintain them without cavities or gum disease.
What’s the best timing for removing wisdom teeth?
Most dental surgeons prefer to wait until the roots of the wisdom teeth are at least one third developed (typically between age 16 and 20) because it is easier to get a hold of them for removal. As you wait longer than that, the roots continue to get longer and more matured and can approach an important nerve in the lower jaw that you don’t want to damage. So, sooner is usually better.
How hard is going to be to have wisdom teeth removed?
Most people are nervous about removing their wisdom teeth because they are afraid of pain or the cost. Recovery is going to be different for everyone. It is really case by case. It is best to visit with your dental surgeon to let them discuss with you your specific situation and the risks and benefits involved. If you generally recover fairly quickly from illnesses, then this will likely apply to this surgery. You may want to take advantage of modern medicine and be sedated so that you are not aware of what is going on. For most people, a combination of over the counter pain relievers will be prescribed by your dental surgeon to keep you comfortable for a few days along with a softer food diet.
