We are officially in the middle of spring and headed for summer and we can't wait! But, before we get into the heat of summer, have you finished your spring cleaning yet? While it's nice to clean out your garage and basement, redo the landscaping and spruce up the kitchen we're talking about a different kind of spring cleaning - a dental cleaning! Below we have a checklist to make sure your oral health is as tidy as your garage this spring!

  • Change out your toothbrush!
    • Did you know that you should be changing out your toothbrush about every 3 months? The average American changes their toothbrush about 1.9 times a year, instead of 4 times a year like the American Dental Association recommends. This is not just a ploy to make you buy new toothbrushes - your toothbrush gets extremely germy along a 3-4 months timespan. Toothbrushes harbor bacteria, meaning that after you are sick you should also change your toothbrush out! Toothbrush bristles can wear out after 3-4 months as well. Once your bristles become matted or frayed it's definitely time to change out your brush. At this point it is no longer cleaning your teeth as effectively as it should, and also it can cause damage to your gums! Since children tend to brush their teeth harder and faster their brushes tend to get matted and worn out quicker meaning that they may need their brushes to be changed out more frequently.
    • When buying your new toothbrush be sure to look for a soft bristled brush. Electronic toothbrushes that you only have to replace the head and not the whole brush are convenient in that they usually save you money in the long run and they are generally better for the environment (only disposing a small tip of the toothbrush as opposed to a whole toothbrush). In today's society of online shopping for things that come straight to your door, many companies make it easy to get new toothbrushes. Some electronic toothbrush companies even have auto-ship every 3 months so that you don't even have to remember when to change your brush head!

  • Check your toothpaste!
    • At some point this spring you will most likely have to buy a new tube of toothpaste. Before you buy your toothpaste make sure that you are using the most beneficial toothpaste possible! When looking for a toothpaste aim to find one that has the ADA (American Dental Association) Seal of Acceptance. The ADA has specific guidelines that must be met to get this seal, meaning that if it has this seal it is most likely a great option for you to use! Be sure to look for toothpaste that has fluoride in it. Fluoride is an extremely important "tooth vitamin" as we like to call it. Fluoride strengthens teeth and helps protect them from cavities! 
    • You should also be sure to check the RDA of your toothpaste, or relative dentin abrasiveness. Your toothpaste should not be too abrasive or it could scrape away your enamel. Toothpastes should be below 250 RDA, but 150-250 is regarded as "harmful" to your enamel. Generally, the lower the better so try to find a toothpaste with RDA below 150 or so! Below we have included a chart with common toothpaste abrasiveness so you can see where your toothpaste falls and whether you should choose a new toothpaste! (For more information on this subject, check out our baking soda blog!)














This chart shows RDA of common toothpastes. 0-70 range is regarded as low, 71-100 is medium, 101-150 is high and 151-250 is regarded as harmful level of relative dentin abrasiveness. Using this chart you can see where your toothpaste falls and whether or not you should switch to a lower abrasive toothpaste!


  • Get your dental cleaning!
    • Our final tip to keep your mouth healthy this spring is to get your spring dental cleaning! Everyone should see the dentist at least every 6 months, however if you need a little extra care we may recommend coming more often. During these cleanings we scale and polish your teeth, making them sparkle and helping prevent cavities! We may also update your x-rays so that we can make sure you don't have any hidden cavities forming or any unusual anatomy in your mouth. Our doctors perform an oral, head and neck cancer physical and you can also get a thorough oral cancer screening using our Identafi. You can get fluoride treatments and also will receive a new toothbrush (which checks another item off your spring checklist)! This dental cleaning will help you ensure your mouth is healthy all spring, so call our office to schedule an appointment if you haven't been in lately or are due for a cleaning.


Springtime is the perfect time to make sure you're staying healthy before the craziness of summer starts. Follow this simple checklist to make sure you and your familes have a healthy, happy, clean spring!

Baking soda has a wide variety of uses such as baking, deodorizing, and many homemade remedies including toothpaste. Different articles have been released over time that claim varying things about baking soda. Some say it's too abrasive and should never be used as toothpaste, whereas others say it's one of the best products you can use! After researching and discussing the details with the doctor's at Dental BLU, we are writing this blog to tell you everything you could ever want to know about using baking soda as toothpaste!


Abrasiveness is the capability of a substance to polish a hard surface by rubbing or grinding. We want the toothpaste we use to be abrasive enough to brush away the stains and bacteria that sit on our teeth, but not abrasive enough to scrub away our enamel itself. Enamel, the hard mineralized surface of the tooth, cannot be regrown or replaced once damaged, so it is important to protect it from toothpaste that is too abrasive. Abrasiveness should not be confused with hardness. For instance, Dr. Rod Kurthy (Founder and CEO of Evolve Dental Technologies) compares your tooth and toothpaste to a diamond and glass. Although both feel very hard, a diamond will easily scratch glass. We attribute this to the Mohs Hardness Scale. Glass is rated a 5 whereas a diamond is rated a 10, therefore the diamond is capable of scratching the softer material, glass. This is similar to baking soda and your teeth. Baking soda feels very hard and gritty; the little pieces have rigid edges that feel rough in your mouth. It seems like this baking soda would damage your teeth. However, on Mohs Hardness of materials scale, tooth enamel is rated a 5 whereas baking soda is rated 2.5. Since baking soda is the softer material, it is not considered very abrasive and it will not harm tooth enamel! The American Dental Association studied Relative Dentin Abrasiveness to determine abrasiveness of various toothpastes. The scale used below shows the low-harmful levels of abrasiveness. 

Low RDA is 0-70

Medium RDA is 70-100

High RDA is 100-150

Harmful RDA is 150-250

The chart below shows the RDA of many common types of toothpaste. Notice that baking soda is only listed at 7, meaning that it is extremely low and therefore a safe, low-abrasive material to use in place of abrasive toothpaste! Look through this chart to see what toothpaste you're using to determine if you should make the switch to lower RDA toothpaste!


Using Baking Soda as Toothpaste

When using baking soda as toothpaste Dr. Depp recommends putting baking soda in a small dish or shot glass, wetting your toothbrush and dipping it in the baking soda, making a thick paste, and then brushing like normal. This thick paste will scrub away stains and bacteria. Baking soda is a great alternative to regular toothpaste for people who are worried about scrubbing away their enamel with abrasive paste, however it should be noted that baking soda does not have fluoride in it, which is important to protect your teeth from cavities. It also does not have the fresh minty taste that many types of toothpaste have, making it less desirable when someone wants fresh-tasting, minty breath!


It is important to be cautious when reading online toothpaste remedies that involve baking soda. A common misconception is that if you mix baking soda with apple cider vinegar, lemon juice, or other acidic substances that it becomes a great tooth whitener but this is incorrect. Acidic materials such as these will harm your teeth more than help them. Acid will eat away at the tooth enamel, softening your teeth and allowing the baking soda to erode away even more of the structure of your teeth causing many more problems like cavities. Harmful combinations with acids like these should not be used. Plain baking soda and water does a fine job at scrubbing away stains and spots. Instead of using a homemade whitening remedy that could be dangerous, if you're looking to have a whiter smile, we offer a variety of whitening options at Dental BLU – call our office to schedule a consultation!



Baking soda is a great product with many uses and we love when our patients use this low abrasive toothpaste to protect their enamel! If you have any more questions about abrasiveness, whitening, or which toothpaste to use, please call our office to schedule a visit. We would be happy to help you!
