Having braces (or Invisalign) will require a few lifestyle changes for most of us. Most of these changes are small, such as closer attention to brushing, flossing, and eating habits, but they are important to keep braces in good condition and teeth healthy. In fact, these are good habits to have regardless of whether you have braces or not!

Food is a wonderful thing, and the huge variety of it is undeniably one of the simplest pleasures of life. Unfortunately, however, many foods are very bad for our teeth, particularly when we have braces. Just by knowing how some foods act on other things around us (think Coke staining a tablecloth or maple syrup sticking to our fingers) we can take a guess on some. Others can be more stealthy.

Let’s take a look at a few types of foods and how they affect teeth and braces:

Hard foods

Hard foods like hard candy, ice, and nuts are hard on teeth and hard on braces. These kinds of foods are like gravel and have the potential to wear down teeth and damage braces. Plus, the sugar in hard candies promote the growth of bacteria which results in cavities.

Sticky foods

Sticky foods like caramel and gum are very bad ideas with braces. They can get stuck between braces or teeth and if not brushed or flossed away soon, can start to damage teeth. While sugar-free gum isn’t bad for your teeth, it’s not a good idea with braces.

Acidic foods

Very acidic foods and drinks like soda, fruit juices, and sports drinks are the worst at promoting cavities. The drinks listed above are doubly harmful because they also contain a lot of sugar, which cavity-causing bacteria love to feed on.

With some patience and a little bit of practice, you can still enjoy your favorite foods whether you have braces or not.

Will your kids’ braces be covered if you sign up for Obamacare?

This question was recently asked to NPR by a 15 year-old as part of an ongoing effort to clarify questions relating to the changes that will happen under Obamacare. Just like any aspect of insurance, the changes resulting from the passage of the Affordable Care Act (Obamacare) are complicated and difficult to approach.

It seems as though there is little change under Obamacare regarding braces. Most dental insurance plans will only cover braces if it affects the patient’s health. For example, if a patient has trouble chewing or if crowded teeth are having a harmful effect on their health, then insurance will be more likely to cover the cost of braces. If the patient simply wants their teeth to look better, however, then insurance will most likely not cover the cost.

That said, pediatric dental coverage is a required coverage area under Obamacare. So if you or your parents are eligible for new or expanded health insurance under the new law, you will be able to get dental care. And if you need braces for health reasons, chances are your insurance plan will cover part of the cost of braces.

As with anything, the best thing to do is shop around to find which insurance suits you best. There is some flexibility offered by Obamacare, so you should be able to compare many different kinds of plans from several different insurance carriers.

The first thing to do when considering braces or another kind of orthodontic treatment is to call for a free consultation. After evaluating your needs, we can answer all of your insurance questions and see whether the cost of braces will be covered, and if so, how much. You have nothing to lose by asking!

While all of us by now are familiar with both traditional braces and Invisalign, not all of us may be aware of what different cases they are used for.

As with any medical treatment, the decision of which tool to use is made on an individual basis by your orthodontist. Since you will be undergoing the treatment and it will affect your smile, you should have as much information as possible before making a decision.

What are the differences between braces and Invisalign?

Very basically, traditional braces use wires and brackets attached to the teeth which are adjusted according to the patient’s treatment needs. Invisalign, however, is a patented system which uses machine-made trays to achieve a similar effect.

Advantages of Invisalign

The main advantage of Invisalign is right there in its name: the trays are near invisible. This is great for patients who don’t want other people to know that they are wearing braces, those who may feel less comfortable in social situations if they had braces, or those who would like to maintain a natural appearance for professional reasons. Additionally, Invisalign trays are removable and they do not affect the wearer’s speech. Invisalign is also a great choice for candidates who would like to close spaces between teeth.

Advantages of Traditional Braces

However, Invisalign does have its limits. Most patients with more complicated orthodontic needs will not always be good candidates for Invisalign. Traditional braces can fix slight problems to the most complicated of issues in a reasonable amount of time. Braces will often be the best choice for patients who need adjustments to their bite.

While they have their differences, both braces and Invisalign are good tools with their own advantages and limitations. For a free consultation with orthodontist Dr. Andy Frost in Creve Coeur, fill out our online form or call (314) 567-1888. We will evaluate your individual needs, desires, and educate you on the best choices for you and your unique smile.



Braces certainly complicate things when it comes to the food you eat, but no matter if you have braces or not, there are many foods that are good for your teeth and many that are not so good.

Tooth decay is ultimately caused by acid eating away at the enamel of your teeth. Orthodontists and dentists will always tell you to brush and floss in order to reduce the amount of plaque buildup on your teeth. Plaque is a layer of bacteria that accumulates on the surface of your teeth. That bacteria then produces acid, which is what causes decay.

Many of the worst foods for your teeth are those that stick to or get stuck between your teeth, and those that contain sugar. Both kinds of food will attract bacteria, which jump-starts the process described above.

The best foods are the ones that either fortify the minerals in your teeth, those that encourage the production of saliva to wash away bacteria, and those that can actually help to remove food particles from your teeth.

Let’s look at a few of the best and the worst, as suggested by a prominent dental school:

Good for your teeth:

Fiber-rich fruits and vegetables are said to have a detergent-like effect in your mouth, and they promote saliva flow. Both of these effects help to clean and fortify teeth.

Cheese, milk, plain yogurt, and other dairy products generate saliva and are good sources of calcium.

Green and black teas both contain polyphenols that either kill or suppress bacteria.

Sugarless chewing gum is a good saliva generator that also removes food particles from your teeth.

Foods with fluoride like fluoridated drinking water help teeth by washing away bacteria and by adding fluoride.

Bad for your teeth:

Sticky candies and sweets stay in your mouth longer and contain loads of sugar.

Starchy foods like soft bread and potato chips can get stuck in your mouth or between teeth.

Carbonated soft drinks contain tons of both sugar and acid, making them extremely harmful to teeth.

In addition to paying closer attention to your diet, good oral hygiene like brushing and flossing is always the best way to prevent tooth decay whether you have braces or not.

When we think of braces, we often think of kids or teenagers. For those of us who grew up in the last 20 or 30 years, we probably knew many kids in school who had braces, or we may even have had braces ourselves. Now we may be considering braces for our own kids as they get older.

But what if you didn’t get braces as a kid? Does that mean you can’t have straight teeth now?

Absolutely not. In fact, adults considering orthodontic treatment are becoming a bigger and bigger part of our market. With so many options ranging from Invisalign to traditional braces, many adults are seeing that having straight teeth may not be as much of an ordeal as it was when they were kids.

Just like kids though, the goals of orthodontic treatment are the first things an adult should consider. For example, do you want “perfect” teeth? That is, are you looking for a purely aesthetic solution? Is there a functional or oral health problem that needs to be addressed? Or do you simply want to protect the smile you have and not allow your current situation to get worse?

The many options currently available for orthodontic treatment also means there are more options to address various problems. For many problems adults face, Invisalign may be the best option. For others, an orthodontic retainer may be most sensible. And still for others traditional braces may be the best route. All of this will depend on the orthodontist’s evaluation of the patient’s individual case as well as the patient’s preference.

Also, don’t be led into thinking that because fewer adults wear braces than kids, adults are more difficult to treat. Both adults’ and children’s teeth present their own challenges, and an orthodontist is trained more than well enough to handle patients of all ages and with all kinds of difficulties and desires.

If you are an adult in St. Louis or Creve Coeur and you are unhappy with the appearance, function, or health of your teeth, stop in to see Dr. Frost for a consultation. We will be happy to give you an honest evaluation and explain your options so you get the best personalized treatment. Contact us to learn more about braces treatment in Creve Coeur!



It is interesting how often unusual orthodontic situations can be discovered with a simple exam and X-ray. Just this week I have diagnosed young children (8 to 10 years of age) with multiple missing permanent teeth and/or supernumerary (extra) teeth.

Both missing permanent teeth and supernumerary teeth are common conditions, and they can only be first seen with an X-ray. This is because permanent teeth form underneath baby teeth long before they ‘push up’ to the surface of the gums. By seeing where and how teeth are forming (as well as how many), an orthodontist can adjust a patient’s treatment plan accordingly.

In the X-ray image below, you can see how clear it is that this patient has several extra teeth coming in below the permanent teeth:

Supernumerary teeth can mean crowding for existing or future permanent teeth, or these teeth could possibly come in at other places in the mouth. A lack of permanent teeth, on the other hand, results in gaps and spaces.

Fortunately, there are many treatment options available whether a patient will have too many–or not enough–permanent teeth. A combination of timely extractions, oral surgery, orthodontic treatment, or cosmetic treatments will make sure a child will have a great looking smile as an adult.

In both cases I saw this week, these diagnoses made a significant impact on the patients’ treatment plans. Although their treatment (braces) will not happen for a year or two, we were able to make sure the treatment works best at that time through the use of X-rays.

Treating a patient whose permanent teeth are still coming in and changing makes this process more difficult. So if your child has not seen an orthodontist by 8 or 9 years of age, please schedule a consultation soon. The earlier your child’s orthodontist knows how his or her teeth will come in, the easier the treatment process will be. It can really make a difference.



An earlier blog, “Does your child need braces twice?” briefly addressed the trend of correcting smiles in two phases, once when a child is between the ages of 6 and 9, and again in the child’s early teens.

Orthodontists know from many studies and from experience that two treatments will not produce a significantly different result, so why is this recommendation still made by dentists and orthodontists?

This is a tough question to answer. First, not all dentists and orthodontists may be aware of the research regarding two phase treatment. Secondly, you are always going to encounter unethical practitioners in any business, and orthodontics is no different. There are some orthodontists that will recommend two stages of treatment for children knowing that while it will not necessarily help anything, it will not hurt anything either (besides the parent’s wallet).

Second, children often want to have straight teeth, and many parents are not averse to treatment before all permanent teeth have come in if it may mean a straighter smile now as well as down the road. Some orthodontists believe there is cultural pressure on kids to have straight teeth–as well as other aspects of their appearance–at younger and younger ages. If well-meaning parents see other young kids with braces and an orthodontist approves, many of them will go along with it, even if it means a higher overall cost.

Even though a first treatment at a young age does not make a difference in most cases, that is not to say that no child could benefit. In exceptional cases such as those which inhibit the normal function of the mouth, early braces would certainly be beneficial. And of course, if a patient wants to improve the look of his or her young smile, that can be done. Problems arise, however, when a young patient or parent is led to believe that early braces are absolutely necessary when that is often not the case.

The fact is that teeth and jaws tend to move back to their original position after correction, especially in growing children. Therefore, it’s crucial that you do your homework, get second opinions, and find a professional orthodontist in St. Louis that you can trust. A good orthodontist will want you to make an informed decision based on what is best for your individual smile. Period.



The most important question your orthodontist can ask at your initial examination is “what can we do for you today?” At our St. Louis orthodontics practice we strive to listen to our patients and their parents and direct our treatment to what is wanted and needed. There are many ways to get from point a to point b–and one size definitely does not fit all. Be assured that we will listen first and act second. We look forward to seeing you in our office and helping you with braces in Creve Coeur.

How often do patients with braces need to be seen in the office?

At Dr. Frost’s office adolescent patients are usually seen every five weeks. Adult patients are usually seen every three to four weeks.  Patients with special circumstances might need to be seen more often. Examples of these type of patients may include those with impacted teeth, patients that need a lot of space closed or patients near the end of their treatment.

Do kids really need braces twice?  It is seemingly more common for orthodontists to perform two phase treatment—or the placement and removal of braces twice. Does this produce a better result?  Orthodontic research has shown that having braces twice  does not produce a better result than one comprehensive phase in the majority of patients. So who does need early orthodontic treatment?  Examples include children with functional problems such as an inability to eat properly, severe crowding or excessive overbites.  The problem and the reason for treatment should be obvious to the parents and the orthodontist should be able to explain the need for and benefit of the treatment. If you believe that your child has a special problem or need a second opinion please call our office and schedule an appointment with Dr. Frost, a St. Louis orthodontist.
