Braces vs. Invisalign


If you or your child needs to fix crooked or crowded teeth, you may be wondering whether braces or Invisalign are the best option. Both are designed to improve oral health and straighten your smile, but which one will work best for you? Below, Seattle dentist Dr. Dean Kois discusses the differences between braces and Invisalign, and the pros and cons of each.     

What They Both Accomplish

Braces and Invisalign trays share common ground in what they are designed to treat. There are pros and cons to each method of tooth alignment, based on patient lifestyle and the severity of the desired correction. Here is a list of issues that both options can correct:  

  • Closing the gaps and spaces between your teeth  
  • Fix overbites, underbites and malocclusion (when teeth do not meet when the jaw is closed)
  • Straighten overlapping or crowded teeth

What Is Invisalign?

Invisalign uses clear aligner trays to gently reshape your smile over time. Custom-fitted, transparent plastic gently shifts your teeth into their proper alignment over the course of 6 to 18 months. Invisalign trays are virtually invisible, prompting many people to choose them for aesthetic reasons. They are also easily removable, allowing you to take them out prior to eating and enabling you to clean them with ease. Because they are easy to remove, there are no issues with food getting caught in the hardware and no need to avoid certain foods, as with traditional braces.

When Are Braces Best?  

Invisalign is designed to treat mild to moderate orthodontic issues. Complex dental issues may require the reinforcement of metal braces to achieve proper alignment. Invisalign also may not be adequate in treating severe overbites, underbites or malocclusions. In some cases, patients who are not disciplined enough to remove Invisalign trays and brush after each meal may also be advised to stick with braces for their orthodontic needs. Patients who are bothered by the appearance of conspicuous metal braces may also opt for clear ceramic (“tooth-colored”) braces.  

The only way to find out which orthodontic option is right for you and your needs is to meet with an experienced dentist and orthodontics expert. To schedule an appointment with Dr. Dean Kois or Dr. Tara Kois to discuss your orthodontic options, call Kois Dentistry at (206) 515-9500.

How Many Dental Implants Can Be Placed at One Time?


Replacing missing teeth is important to maintaining good oral health. Even one or two missing teeth can lead to serious problems down the road. If left untreated, gaps in your smile could lead to shifting teeth, a deteriorating jawbone and even gum disease. In this blog post, trusted Seattle dentist Dr. Dean Kois answers questions about how many dental implants can be placed at one time.   

Reasons for Dental Implants  

There are many reasons why people consider getting dental implants. Below are a few of the primary motivating factors for choosing implants:  

  • Stop teeth from shifting. The teeth surrounding a gap will begin to shift over time to fill in the empty space. Unevenly spaced teeth can cause bite problems and oral health issues as it is more difficult to keep them clean.  
  • Keep your jawbone healthy. Unlike dental bridges, implants stimulate the bone beneath the tooth, preventing the jawbone from deteriorating.    
  • Preserve facial structure. If your jawbone deteriorates, your face can begin to appear sunken over time. Thin lips and sunken cheeks can make you look much older than your natural age. 

How Many Implants Should You Get?

Depending on your needs, dental implants can be used to replace a single tooth up to an entire row. One or two missing teeth will require one implant per tooth. If you require two or more missing teeth to be replaced, fewer implants may be used to anchor the teeth. Depending on the placement of the implants and the volume of bone density in your jaw, as few as two implants can be used to support a four-tooth bridge. For implant-supported full arch dentures, as many as eight and as little as four implants may be used.

Your Overall Health

While it is possible for a healthy patient to have multiple implants placed at once, there are several factors at play in determining whether or not you are a good candidate for dental implants. Bone volume and structure must be evaluated to avoid issues surrounding bone atrophy. The patient also must not exhibit signs of periodontal disease, as this can obstruct the healing process. Your dentist will be able to evaluate your oral and overall health and help you decide if dental implants are right for you.    

Only a trip to the dentist will help you determine if dental implants are a viable option for you. To schedule an appointment with Dr. Dean Kois or Dr. Tara Kois, call Kois Dentistry at (206) 515-9500.

Start the New Year Right: Tips for Healthier Teeth


As the excitement and indulgence of the holiday season come to an end, the New Year marks an excellent time to reinforce good habits and set new goals for self-improvement. Proper oral hygiene promotes good overall health as well as a great smile. In this blog post, top Seattle dentist Dr. Dean Kois discusses ways to start the New Year right with tips for healthier teeth.

Brushing and Flossing

Regular brushing and flossing lay the groundwork for happy teeth and gums. Follow these tips to ensure you are cleaning your teeth properly:   

  • Brush at least twice a day. Frequent brushing prevents the buildup of harmful acids that break down tooth enamel.  
  • Place your toothbrush at a 45-degree angle to your gum line, and brush in a back-and-forth and up-and-down motion.
  • Use a brush with soft or medium bristles. Avoid hard bristles that can irritate the gums.
  • Floss daily. Your toothbrush alone cannot reach between all your teeth.
  • Don’t forget to brush your tongue. Brushing your tongue removes bacteria that can negatively impact your teeth and cause bad breath.

Eat Healthy Foods

Sugars convert into harmful, enamel-eroding acids in your mouth. This causes cavities and weakens your teeth. Not only does a healthy diet help you stay fit, it also promotes good oral hygiene. You don’t have to cut out sugary snacks entirely, but keep them to a minimum and brush soon after you eat them. Snacking on crunchy vegetables and fruits, such as carrots and apples, can help clean your teeth by removing previously built up food residue.      

Avoid Sugary Beverages

Sodas, coffee, alcohol and even fruit juice can all negatively impact your teeth, due to the high levels of sugars and acids they contain. Water is always the best way to rehydrate, but if you choose to drink something sweet or alcoholic, make sure to rinse your mouth out with water soon afterwards to minimize buildup. Drinking milk is also safe for your teeth, and delivers a good dose of calcium and vitamin D to your body, which helps promote healthy teeth, bones and gums.

Good oral hygiene starts at home, but regular trips to the dentist are also necessary to ensure a healthy smile. To schedule an appointment with Dr. Dean Kois or Dr. Tara Kois, call Kois Dentistry at (206) 515-9500.

How to Choose a Dentist

Choosing a dentist

Finding the right dentist can help you build a lasting relationship that benefits your dental health. When you feel comfortable and trust your dentist, you’re more likely to make all of your regular appointments, which means you’ll have a healthier, brighter smile.

The trusted Seattle dental team at Kois Dentistry understands that choosing a dentist is an important decision. In this post, our dental team discusses their recommended strategy for choosing the right dentist.

Research Dentists in Your Area

Start by searching for dentists that are easily accessible. Picking a dentist near your home or office makes it easier to show up for your appointments. Some dentists have multiple offices, which allows you to choose the most convenient location.

You should also look at a dentist’s experience and what their patients are saying about them. Many dentists will have patient testimonials that provide insight into how their dentists handle specific patient issues.

Find a Dentist That Matches Your Unique Needs

If you have a specific dental problem that you need fixed, make sure your dentist has experience handling these issues. For example, patients who experience fear or anxiety when going to the dentist may want to find a dentist that offers sedation dentistry.

If you have specific cosmetic dental needs, such as veneers or teeth whitening, look for dentists that regularly handle cosmetic issues. It’s also a good idea to look at before and after photos so you can get a good idea of the cosmetic dentist’s skill and what results to expect. Once you’ve identified the dentists that fit your criteria, it’s time to give their office a call.

Call Your Dentist’s Office or Visit Them in Person

Call your new dentist’s office to ask them about their specific services, payment options, and other concerns you have. Your dentist should begin with a comprehensive exam on your first visit, where they will identify any dental issues and discuss possible treatment options.

At this point, you need to decide if you feel comfortable with your new dentist and trust them to be your partner for long-term dental health. Once you’ve found the right dentist, staying on track with good dental habits will be a much easier process.

Call to Schedule Your New Patient Visit

A patient’s first visit is a time to build trust and make sure you feel at ease with your new dentist. The trusted dental team at Kois Dentistry will give you a comprehensive dental exam and discuss treatment options for improving your dental health. To schedule your first visit, please call (206) 515-9500 today.

What's Behind Your Bad Breath?

What causes bad breath?

Bad breath — technically referred to as halitosis — can be the result of poor dental habits, eating certain kinds of foods, or any number of diseases. In many cases, you can reduce or eliminate bad breath by practicing good dental hygiene. It’s also a very good idea to consult with your dentist to determine the cause of your bad breath.

The dental team at Kois Dentistry handles many questions from patients about bad breath. In this post, our dental team discusses some of the common causes of halitosis and how to reduce bad breath.

Causes of Bad Breath

Food particles that are stuck in or between your teeth can promote bacterial growth that causes bad breath and other dental problems. Tobacco use can also cause bad breath, in addition to staining your teeth and bothering your gums.

Many cases of bad breath are caused by poor dental hygiene or dietary habits. However, bad breath can also be a symptom of some diseases, such as gum disease. You should consult your dentist if you are concerned about your bad breath and need help determining its cause.

How to Fight Bad Breath

You can reduce or eliminate many cases of bad breath by committing to the basics of good dental hygiene. You should be visiting your dentist at least twice a year, but most of the work must be done at home.

The following habits can help prevent bad breath, along with many other dental problems:

•    Brush twice a day at a 45-degree angle to your gum

•    Brush or scrape your tongue

•    Floss regularly, at least once a day

•    Note if there are certain foods that trigger bad breath and consider avoiding or reducing consumption of these foods

If you have dentures, you can also be susceptible to bad breath if you do not remove them regularly to clean them. Be sure to follow your dentist’s recommendations regarding the proper care and cleaning of your dentures.

Follow these tips to prevent halitosis, and consult your dentist if you are having persistent issues with bad breath.

Discuss Bad Breath with Your Dentist

If you have questions or concerns, talk to your dentist about your issues with bad breath. The trusted dental team at Kois Dentistry can help identify both the cause of and solution to your bad breath problems. To schedule a one-on-one consultation, please call (206) 515-9500 today.

How to Get a Picture-Perfect Wedding Smile

Wedding Smile Makeover

If you’re like most brides- and grooms-to-be, making sure you have a picture-perfect smile is probably an important part of your wedding plan. All the attention is going to be on you — and your smile. To get a radiant smile on your big day, there are a few things you should be doing in the weeks and months leading up to the ceremony.

The trusted team at Kois Dentistry understands how much a great smile can affect how you feel and how you’ll remember your wedding day. In this post, our dental team shares their tips for getting a picture-perfect wedding smile.

Start with a Customized Whitening Plan

An effective teeth whitening treatment should be your top priority for improving your smile before your wedding day. Over-the-counter whitening trays or toothpastes are typically not very concentrated, and won’t give you the dramatic results you want for one of the biggest days of your life.

The most effective whitening method is a chairside whitening treatment with an experienced cosmetic dentist. If you have discoloration due to age, drinking dark-colored beverages, tobacco use, or other reasons, this is the best whitening option available, and it usually takes an hour or less.

You can also get customized whitening trays from your dentist. These are molded to fit your teeth without shifting around, and they can be used at home. Keep in mind that these trays take a few weeks to produce results, so plan accordingly to maximize your smile on your wedding day.

Upgrade Your Smile with Porcelain Veneers

Veneers can be used to even out the edges of your teeth and make your smile look even better. If you have any chipped or cracked teeth, gaps, or crooked teeth, getting porcelain veneers can fix these issues. Veneers look like natural teeth and can last for many years with proper care.

Once you’ve evened out the edges or your teeth and used an effective whitening treatment, you’ll be ready for your wedding day with a smile that everyone will remember.
