An abundance of sweets during the holidays increases the threat of cavities and tooth sensitivity. Researchers have found a way to regrow enamel to protect teeth. Perhaps one day their gel could be used as teeth strips or in a mouth guard, they say.

Ten Factors to Consider in the Restorative Process
The fracturing of porcelain is most often related to one of these ten factors. Having a thorough understanding of the masticatory system is critical for obtaining a predictable result. The Dawson Philosophy of Complete Dentistry teaches a protocol for producing healthy tissues, restorations that can be easily and thoroughly cleaned by the patient, occlusal contacts in harmony with the masticatory system and optimum esthetics.
1. Properly Designed Centric Stops Equal intensity centric holding contacts distribute forces equally through out the mouth. The centric stops also create vertical and horizontal stability of the teeth. For posterior teeth, the goal is a cusp-fossa occlusal relationship. A porcelain restoration that is left high or with a poorly designed stop will lead to porcelain that is overloaded. Often the first sign of occlusal instability of an allceramic restoration is fracture.
2. Correct Lateral Anterior Guidance When the mandible moves laterally, the goal is to have immediate disclusion of the posterior teeth on the working and balancing side. When posterior teeth are allowed to contact in excursive movements, increased muscle activity, combined with the increased mechanical stress contributes to increased chance of fracture. Creating the correct contour on the lingual of the maxillary canines is one of the most important decisions a clinician makes during the restorative process. If the cuspids are too steep for the patient’s functional pattern, fracture, mobility or migration is likely.
3. Correct Protrusive Anterior Guidance The goal of any protrusive movement of the mandible is immediate posterior disclusion. As the mandible moves forward, the goal is to have equal contact of the leading edge of the lower incisors from the centric stop to the maxillary incisal edge. Balancing the protrusive load over the lingual contours of the central and lateral incisors is key to the comfort and stability of anterior esthetic restorations.
4. Correct Crossover Disclusion It is not by chance that the most common anterior esthetic restoration to fracture is maxillary lateral incisors. Proper occlusal design dictates a smooth transition to the incisal edge of the maxillary centrals as the patient moves beyond the cuspid in lateral excursion. When this positioning is overlooked, excessive loads can be placed on the distal of the lateral incisors, leading to fracture.
5. Lingual Contours In Harmony With The Envelope Of Function Protecting the posterior teeth from contact in excursive movements is one of the most important functions of the anterior teeth. Some patients’ functional patterns are steep while other patients’ are more horizontal. Signs of instability such as wear, fremitus or migration of the anterior teeth are all signs a constriction could be occurring . Why Porcelain Breaks and Chips Ten Factors to Consider in the Restorative Process.
6. Parafunction Bruxism, nail biting, sleep disturbances, chewing on pencils/pens, or any aberrant movement of the mandible that brings the teeth together in an abnormal pattern and creates signs of instability in any part of the system must be identified during treatment planning.
7. Properly Designed Tooth Preparation One of the most common causes of fracture is over reduction of the incisal edge. Proper treatment planning with mounted diagnostic casts, photographs, radiographs, and a complete exam process allows the restorative team to create a three-dimensional diagnostic wax up for creation of preparation reduction guides.
8. Properly Finished Tooth Preparations When a sharp line angle is left on a preparation, it will not get transferred properly to the die, leading to a porcelain restoration with a rounded internal surface abutting the sharp line angle. This abutment creates tremendous stress on the porcelain substructure, and when combined with poor occlusal management, may lead to fracture.
9. Meticulous Adhesive Technique Poor attention to detail during the delivery phase of all ceramic restorations is a major cause of postoperative discomfort and fracture.
10. Trauma The use of a sports guard, like the one shown from Great Lakes Orthodontics, should be provided for the patient with leisure or job-related activities that pose a risk to the dentition.
Lack of regular brushing and flossing leaves small food particles wedged between the teeth that collect bacterial and emit chemicals, like hydrogen sulfide – the same compound that gives rotten eggs their characteristic smell.

Bruxism sounds like a scary dental term but what it translates to in simple English is ‘teeth grinding‘. Too many people grind their teeth every day, whether it’s because of a bad habit, from the anger and frustration of life’s struggles, or because of too much excitement. The real problem is that people tend to grind their teeth in their sleep too. According to to the Canadian Sleep Society, approximately 8% of adults and close to 13% of children experience sleep bruxism.
Some common signs found in daily teeth grinders include headaches, earaches, tooth sensitivity, and pain in the jaw area. When you clench or gind your teeth, you are exerting a massive amount of pressure on your teeth. If bruxism is allowed to persist for too long, some serious dental complications can develop such as cracked or chipped teeth, broken teeth, and even severe damage to the temporomandibular joint of the jaws.
But how do you prevent something that most don’t even realize they’re doing? The first thing is diagnosing the problem. This can easily be done through your regular dental visits. Notify your dentist if you suspect you or your child of grinding their teeth, especially if some of the symptoms mentioned before become recurring ones. Your dentist will be able to monitor your mouth and see if there are any particularly alarming amounts of wear on the surface of the teeth.
The next step is prevention. As difficult as it may sound for some, especially ones who have developed bruxism as a bad habit, this is nonetheless extremely important. Always be aware if you are clenching or grinding your teeth during the day, and if so, try your best to regulate this behaviour. Your teeth should always be apart during the day. Try to find stress reducing activities such as exercise, calm music, and reading in order to relax yourself from too much excitement and reduce the urge to clench or grind. On top of that, be sure to decrease your caffeine intake before bed, as this extra jolt of excitement can lead to sleep bruxism. In the worst of cases, your dentist might recommend wearing a custom-fit nightguard. This device works by reducing the pressure forced onto the teeth during sleep and reduces wear.

Your teeth are with you for life. They make you look good when you smile and help you break down food so you can stay alive. They are important for all of us, so why not take care of them with good dental hygiene? I know what you’re thinking: here we go with another speech about how I need to take better care of my teeth. Not true. Here is an article of 10 things that almost everybody does that damages teeth. Most of the time we don’t even realize it either.
1. Crunching Ice: We get it, it’s almost like a snack. It cools you down and it’s just water too, so zero calories! What could possibly be wrong with chewing on ice? Well, actually it can be pretty bad for your teeth. Chewing on ice has a chance of causing cracks in your teeth, which can be difficult to fix. It seems as if human teeth are not designed to chomp or crush solid objects like ice. This extends to hard candy and rice as well.
2. Thinking that Mouthwash can Replace Flossing: I know, I know. This might be another lecture about flossing (ok it is). The fact of the matter is, using mouthwash is just not enough to protect yourself against gingivitis, yet everybody believes that it is, mostly because that burning sensation – if you’re using Listerine – means everything’s A-ok. In order to kill ALL the bacteria between teeth and gums, you just need to floss.
3. Drinking Sports Drinks: Sports drinks like Gatorade and Powerade are designed to fill you with electrolytes after a potentially rough workout. But what they also fill you with is sugar. You may already be aware that sports drinks contain a lot of sugar, but what you may not know is that with a dry mouth, more bacteria is created. This bacteria feeds off of sugar and creates cavities in your mouth. This is bad.
4. Drinking Soft Drinks: We all love a nice can of Coke, Sprite, Root Beer, etc., especially with summer coming along. Aside from all the sugar, these drinks contain a lot of acidity, which react badly when they come in contact with your teeth. This erodes enamel and ultimately does irreversible damage to your teeth.
5. Using your Teeth as Tools: If you have scissors, a can opener, or a pair of pliers with you, please use them and not your teeth to perform tasks. It may seem convenient, but even something like cutting a piece of thread with your teeth can cause micro-fractures which may lead to bigger problems down the road.
6. Grinding your Teeth: One of the most popular bad habits in the world. People grind their teeth all the time: when they’re upset, nervous, or even bored. Clenching your jaw is the same thing. They are both horrible for your teeth, especially when you might be doing these things in your sleep. Hours and hours of unwanted pressure on the teeth is never a good thing. If you think you might be a tooth grinder or clencher, start practising some self-control and maybe get a night guard for bedtime.
7. Biting Things: For the same reasons listed above, you might also be one of those people who chews and bites on their pen, pencil, finger, whatever. Pressure marks, cracks, and even breaks can result from keeping your mouth and teeth closed on a solid object for extended periods of time.
8. Biting your Nails: This is becoming a little bit of a pattern isn’t it? Besides the cracks and breaks caused from chewing solid objects for long durations, disgusting germs that live under your fingernails can enter your teeth, which may infect your teeth and gums. Nasty stuff.
9. Using the Wrong Tools for the Job: You might hate me for saying this but toothpicks are bad for your teeth! Also, so are paper clips, pieces of paper, or other foreign objects you may want to clean your teeth with. Not only do they not work as well as simple dental floss, you can end up seriously hurting your gums with those things.
10. Skipping the Dentist: So you brush twice a day, floss, and follow all the best oral care tips, but you skip dental cleanings and other procedures. It’s the same as not doing anything at all. Seriously, not going for cleanings or essential dental repairs will come back to haunt you. Make your teeth glad to be a part of your gorgeous mouth and go see your local kitsilano dentist when it’s time! And if that’s us, GREAT!
