4 Simple Tips to Have a Great Smile

2017-05-31 20:16:00 orianablieu
  1. Brush   It is surprising how many people still do not brush twice per day. I often hear that people think it is most important to do it before bed or just after waking up. The reason for brushing is not just to stop bad breath. It is to clean your teeth and gums from food debris and plaque. Plaque never stops forming. Dental plaque is made up of different kinds of bacteria. Buildup of these bacteria lead to cavities and gum disease.

2. Floss using the C-method I always urge people to curve the floss and go under the pink triangles of gum. That is where all the plaque likes to hide.

3. Whitening White teeth have long been considered a sign of good health and beauty. Some of us are born with naturally beautiful white teeth. For everyone else there is Teeth Whitening. There are many products out there that promise to make smiles brighter. A simple and natural way to whiten teeth is to use a combination of baking soda and Hydrogen Peroxide. Just a little of each can remove surface stains and polish enamel. Whitening strips are also available by Crest or in our office for professional quality Opalescence. Teeth also stay whiter with regular cleaning with toothbrush and floss.

4. Wear Red Lipstick Maybe this is a better option for the ladies, but red or bright colored lipstick can make teeth look brighter. It also draws attention to the face. A smile in general shows confidence…and confidence is always beautiful.

Have a great summer!

Happy Chinese New Year 2017!

2017-01-25 18:09:08 orianablieu
Xīn Nián Kuài Lè! Gōngxǐ Fācái!  Chuc mung năm mới!  Happy Chinese New Year! Happy Lunar New Year!
February is here, and that means it’s time to celebrate Chinese New Year (CNY). Every CNY marks the arrival of spring in China, which means it’s time to clean house, break out the fireworks and honor one’s ancestors. It is a celebration revered in many countries throughout the world; including the U.S. We all know how famous the Chinese New Year parade is in San Fancisco. In honor of this year’s CNY celebration we’d like to fill you in on a few contributions the Chinese brought to the dental world, many many years ago!
Some of the Biggies
1.  Dental Fillings: During China’s Tang Dynasty period, the Chinese developed a method for filling cavities that involved heating portions of silver and tin in a large pot, and pouring that mixture into a person’s decayed tooth. Ouch! When did they figure this out? Sometime around 659 A.D. The next closest use of this sort of dental amalgam was by a “Dr. Stockerus” in Germany in 1528. That’s almost 900 years later. Wow!
2.  The Bristled Toothbrush: How would you like to brush your teeth with a piece of bone or bamboo stuffed with neck hair plucked from a boar? Sounds yummy, right? Well, in 1498 the Chinese started doing just that, after inventing the very first “bristled” toothbrush. 
Bristle brushes were so unique, in fact, that mass production of them didn’t begin until England took a stab at it in 1780. Americans were even further behind, avoiding mass production until 1885. Before the bristled toothbrush, most societies used what is known as a “chew stick” that frays at the ends and produces a degree of friction across the surface of teeth to dislodge food and debris.
3.  TONS of Other Things: The compass, paper money, gunpowder, the kite (thousands of years before kites appeared in Europe), food … water … okay, we’re joking now. Pretty incredible, right? As a launching point for more info about the wonderful contributions of China’s people to world history and achievement, check out this page on Wikipedia.
Have a great “second” New Year! Try those resolutions on for size again!

Remember Blue Apple Dental Group if you are looking for a dentist that doesn’t give you horse hair toothbrushes after your dental hygiene visits.

Be well!

Ouch! What to Do About Sensitive Teeth

2016-12-09 21:10:10 orianablieu

Even though winter is here, and most of the country is trying its best to stay away from just aboutsensitive_teethanything cold, hordes of ice cream lovers across the nation show no concern for the temperature outside when it comes to indulging in their favorite treats. From the mildly chilly winter of southern Florida, to the deep freeze of Alaska, you don’t have to look far to find an American enjoying an icy treat even in December. Nor is there much of a search needed to find a person who has to dance around that ice cream cone because they’ve got sensitive teeth. Want to avoid a similar predicament, or reduce sensitivity if you’re one of the unlucky millions? Here’s how …

Prevent, or Slow the Onset of Sensitivity

  • Turn down the aggression. Many of us brush our teeth as if we’re scrubbing in for surgery – far too rough for the few millimeters of enamel that protects the dentin beneath. While plaque is sticky, removing it doesn’t require the sort of effort most of us put forth. Brushing your teeth should almost feel as though you were massaging your gums instead of scrubbing them, and you should never brush with a back and forth saw-like motion. This all-too-common method of brushing is perhaps the most frequent cause of gum recession not tied to disease, and it literally carves grooves in the enamel of your teeth. If you brush gently and in a circular motion, aiming the head of the toothbrush at an angle toward the base of the gums, you’ll be in good shape. Ask your dentist for a lesson in proper brushing if you’re afraid you’re not doing it correctly. This single tip can help you avoid sensitivity and help stall its progress, if you’re already a sufferer.
  • Take care of your gums. As unwise as it is to take your aggression out on your teeth, ignoring them has a similar effect when it comes to sensitivity. Because this condition is a result of dentin exposure, those with receding gums are also likely to experience its symptoms. Since our teeth are only covered by enamel to a point just below the gum line, any recession to the gum line exposes the dentin. We all know the drill on preventing gum disease. Brush regularly, see your dentist, and floss daily. These are the three golden rules, and they can save you from tooth sensitivity, and a host of other problems later on.

Are You a Grinder?

gum-line-fillings-b4afterMany people notice slight sensitivities to cold in different places from time to time. If you are clenching or grinding your teeth, you cause abfraction lesions. Abfractions are tiny chips in the enamel right at the gum line. With enough clenching and grinding, those tiny invisible chips turn into notches and the tooth and root become weakened.

Bonding can be a quick and easy way to repair those brown spots and provide more support and protection to the teeth.


How Do I Fix This?

  • Try an over-the-counter toothpaste for sensitive teeth. Sensodyne, Clin Pro or other such toothpastes have ingredients that help to either “seal off,” the exposed “pores” of your dentin, or desensitize the nerve in a way that minimizes its reaction to triggers.
  • Follow the two tips above that for those interested in preventing sensitive teeth. Both steps can help lessen your sensitivity over time.dental_services
  • Ask your dentist for a cover-up. For some, the application of a fluoride varnish, veneer, or certain types of bonding can effectively cover up the exposed area, and act as a barrier to exposure. These procedures are quick and simple, and can make a world of difference if nothing else works for you. Such efforts also have the added benefit of protecting your tooth from further erosion, which is good if you’re prone to aggressive brushing.

Sensitive teeth are a nuisance. So, be proactive and protect your teeth now if you’re not a sufferer, and, if you are, take the right steps to stall its progress. Ice cream, any time of the year – every year – is, after all, a good thing.

Is Anxiety Stopping you from Tooth Care?

2016-07-20 21:25:52 orianablieu

By Oriana Lieu


comfortIf you have anxiety about visiting the dentist, you’re not alone. Research suggests one out of every five Americans have the same apprehension. I understand how past experiences might have left you uncomfortable. If you avoid going to the dentist, you place yourself at greater risk for gum disease, oral cancer and tooth decay that your dentist or hygienist can spot at a periodic visit.

We have seen everything here in the office regarding different levels of anxiety and fear of dentistry. Some people can’t do anything unless they are fully sedated. Some take a medication to relax them before their appointment. Some self medicate with Marijuana or other drugs. One option that can help reduce anxiety and make your visit a pleasant one is Nitrous Oxide.

Nitrous Oxide is a colorless and nearly odorless gas used in dentistry to reduce anxiety, pain and gagging during procedures. You may know it under its more common name – laughing gas. It is delivered via tubing connected to a small “mask” that is placed over your nose, and offers varying degrees of sedation that range from mild tingling and euphoria to drowsiness.

You’ve likely heard of nitrous oxide before, and perhaps even benefited from it in the past if you’ve had your wisdom teeth removed. It has been a fixture in dentistry since its discovery in 1772! Most people don’t realize, however, that it can be used for all types of procedures – even cleanings – given the degrees of flexible sedation it provides. I have even heard that some hospitals use it during childbirth for women in labor.

Having a good relationship with your provider is also a key to reducing dental anxiety. Being able to ask questions with the dentist, treatment coordinator, hygienist or dental assistant is also key. Sometimes people are scared to ask the dentist so getting info from other trained and knowledgeable staff is a great resource. Videos can also give you background info to help ease fears. Whatever it is, it is helpful to talk with your dentist or hygienist about your concerns or fears before your appointment so they can be sure to address those when you do have dental treatment done.

So, eliminate your fear of the dentist once and for all, and ask us about nitrous oxide treatment or other anxiety management medications at your next visit. Or, call today to schedule an appointment if you’ve been hiding from us for a while!

I'm Pregnant! How Does this affect my teeth and gums?

2016-06-15 23:49:16 admin

imagesWhile pregnant, in between trips to the doctor, hospital tours and setting up the nursery, don’t let visiting the dentist fall off your  to-do list!  Getting a checkup during pregnancy is safe and important for your dental health. Not only can you take care of cleanings and procedures like cavity fillings before your baby is born, but your dentist can help you with any pregnancy-related dental symptoms you might be experiencing.

These are the most common concerns women have about going to the dentist during pregnancy.

1.  When Do I Tell My Dentist I Am Pregnant?

Even if you only think you might be pregnant, let your dental office know. Tell them how far along you are when you make your appointment. Also let your dentist know about the medications you are taking or if you have received any special advice from your physician. If your pregnancy is high-risk or if you have certain medical conditions, your dentist and your physician may recommend that some treatments be postponed.

2.  How Might Pregnancy Affect My Mouth?

Although many women make it nine months with no dental discomfort, pregnancy can make some conditions worse – or create new ones. Regular checkups and good dental health habits can help keep you and your baby healthy.

Pregnancy Gingivitis
Your mouth can be affected by the hormonal changes you will experience during pregnancy. For example, some women develop a condition known as “pregnancy gingivitis,” an inflammation of the gums that can cause swelling and tenderness. Your gums also may bleed a little when you brush or floss. Left untreated, gingivitis can lead to more serious forms of gum disease. Your dentist may recommend more frequent cleanings to prevent this. Many dental insurances also cover an extra cleaning during pregnancy.  Also, gum disease has been linked to low birth-weight in babies, so it is also good for baby’s development to keep mom’s gums healthy.

Increased Risk of Tooth Decay
Pregnant women may be more prone to dental decay for a number of reasons. If you’re eating more carbs than usual, this can cause decay. Morning sickness can increase the amount of acid your mouth is exposed to, which can eat away at the outer covering of your tooth (enamel). Click here to see more ways to eat healthy to reduce risk of cavities.

Brushing twice a day and flossing during the day can also fall by the wayside during pregnancy for many reasons, including morning sickness, a more sensitive gag reflex, tender gums and exhaustion. It’s especially important to keep up your routine, as poor habits during pregnancy have been associated with premature delivery, intrauterine growth restriction, gestational diabetes and preeclampsia.

Pregnancy Tumorspreg tumor
In some women, overgrowths of tissue called “pregnancy tumors” appear on the gums, most often during the second trimester. It is not cancer but rather just swelling that happens most often between teeth. They may be related to excess plaque. They bleed easily and have a red, raw-looking raspberry-like appearance. They usually disappear after your baby is born, but if you are concerned, talk to your dentist about removing them.

3.  Are the Medications My Dentist May Recommend Safe During Pregnancy?

Be sure your dentist knows what, if any, prescription medications and over-the-counter drugs you are taking. This information will help your dentist determine what type of prescription, if any, to write for you. Your dentist can consult with your physician to choose medications—such as painkillers or antibiotics—you may safely take during the pregnancy. Both your dentist and physician are concerned about you and your baby, so ask them any questions you have about medications they recommend.

4.  What About Local Anesthetics During Pregnancy?

If you’re pregnant and need a filling, root canal or tooth pulled, one thing you don’t have to worry about is the safety of the numbing medications your dentist may use during the procedure. They are, in fact, safe for both you and your baby.

A study in the August 2015 issue of the Journal of the American Dental Association followed a group of pregnant women who had procedures that used anesthetics like lidocaine shots and a group that did not. The study showed these treatments were safe during pregnancy, as they cause no difference in the rate of miscarriages, birth defects, prematurity or weight of the baby. “Our study identified no evidence to show that dental treatment with anesthetics is harmful during pregnancy,” said study author Dr. Hagai. “We aimed to determine if there was a significant risk associated with dental treatment with anesthesia and pregnancy outcomes. We did not find any such risk.”

5.  Can I Get a Dental X-Ray While Pregnant?

About half of the women in the anesthetic JADA study had X-rays taken while they were pregnant, which were also found to be safe. It’s possible you’ll need an X-ray if you suffer a dental emergency or if there is a need to diagnose a dental problem. Although, radiation from dental X-rays is extremely low, your dentist or hygienist will cover you with a leaded apron that minimizes exposure to the abdomen. Your dental office will also cover your throat with a leaded collar to protect your thyroid from radiation.

Congratulations and take care of yourself. A happy and healthy Mama makes for a happy and healthy baby!
