Perhaps the Tooth Fairy should start looking for a new job! Researchers have had success in locating stem cells in dental tissue and in regenerating new dental tissue. Dental stem cells have the potential to grow not just teeth, but also show promise in the repair of bone tissues and optic neurons. In fact, there are now companies that will extract stem cells from wisdom and baby teeth and store them for you until needed, a process similar to cord-blood banking. This is an exciting discovery with enormous potential, but is it worth the expense to invest your child’s teeth now? We decided to look in to this further.
What’s so Special About a Stem Cell?
Stem cells have the remarkable potential to grow into many different types of cells as well as aid the body’s internal repair system. For example, a stem cell can become another type of cell with a more specialized function, such as a muscle cell or a brain cell. Stem cells have been found in bone marrow and in umbilical cord blood, and in 2003 were also found in teeth.
Scientists at the National Institute of Dental and Craniofacial Research noticed that when a tooth gets a cavity, it also produces something called reparative dentin to protect itself. This led researchers to hypothesize that stem cells were within teeth activating the dentin when needed. Having the ability to create dentin could allow a dentist to grow replacement teeth as needed, rather than rely on implants or bridges. Even more potential lies in the stem cells that have been found in baby teeth, known as SHED (stem cells from human exfoliated deciduous teeth). SHED cells also seem to be able to make something similar to bone.
Enter tooth banks, which promise to safely extract the SHED cells from your child’s baby teeth and store them for later use.
How do Tooth Banks Work?
Extracting SHED cells from baby teeth is a process that involves the cooperation and expertise of your dentist. Rather than wait for a child’s loose baby tooth to fall out, it’s best to extract the tooth when there’s about one-third of the root remaining to ensure there are viable stem cells. According to the former American Academy of Pediatric Dentistry (AAPD) President Dr. Jade Miller, “It really requires some planning, and so parents need to make this decision early on and be prepared and speak with their pediatric dentist about that.” Tooth banks offer a dental kit for the dentist with all the necessary components to collect the SHED cells.
From there, the tooth bank extracts the stem cells from the dental pulp inside the tooth, and then processes and tests the cells before they are cryogenically preserved.
What do the Experts Say?
Currently, the scientific community is divided as to whether or not storing teeth is worthwhile. The AAPD released an official statement saying it “recognizes that harvested dental stem cells is an emerging science which may have application for oral health care but at present there are no treatments available using harvested dental stem cells from a tooth or follicle. As the technology continues to evolve, the process of procurement of dental stems should be accomplished only with deliberate integrity and appropriate informed consent to assure the highest ethical standards and quality of outcomes.”
Meanwhile the AAPD’s former president, Dr. Miller has decided, as a grandparent, to use a tooth bank. “It’s really in its infancy, much of this research. There’s a very strong chance there’s going to be utilization for these stem cells, and they could be life-saving. There’s going to be a significant application and I want to give my grandkids the opportunity to have those options.”
Says Dr. Brunacini: “Stems cells are exciting in their potential to help a lot of people with multiple ailments, including missing teeth. Here at FDA, we are excited to see how the technology progresses to hopefully provide an all-natural approach to replacing missing teeth.”

Losing a tooth is an exciting rite-of-passage when you are young, but as an adult it is a cause for concern. It is also common: most adults will lose teeth to decay, gum disease or injury. Losing teeth not only affects your smile but also impacts your bite and your jawbone. Fortunately, there are options! Here at Falmouth Dental Arts, we can address tooth loss with a dental implant or with bridges. We aim to make every process as comfortable and safe as possible, and we will help you to determine which choice is right for you. Here is some more general information about these two options.
Implants
The American Dental Association (ADA) recommends implants as the standard replacement for missing teeth. Implants look and feel like natural teeth and are designed to last a lifetime. However, you do need a healthy jawbone and soft tissue to be a candidate for dental implants.
If an implant is right for you, the first step is to place a titanium implant in your jaw. The implant replaces your tooth root and will naturally fuse to your jawbone over the course of several weeks. Once that is firmly in place, a titanium post will be added to serve as an anchor for a crown.
Bridges
A bridge is a good option for replacing a few teeth. It involves fusing artificial teeth to a metal frame. The frame is then cemented to supports, which are either implants or healthy teeth covered with crowns. There are limits, however, to how many teeth a bridge can replace. Generally, a bridge is a less-invasive procedure but does not last as long as an implant. The average life of a bridge is 10 years.
The Future
There is also an exciting third option on the horizon! Researchers have found a way to grow teeth from dental tissue stem cells. We will delve in to this possibility in our next blog post…stay tuned!
As always, the best way to prevent tooth loss is to practice good oral hygiene and visit your dentist regularly. However, tooth loss happens. If you have lost a tooth or have concerns about your teeth, please give us a call at 207.781.5900. We are happy to discuss your options as we truly believe that having healthy teeth is an integral part of comprehensive health care.

Teeth and health change over time. Different stages of life have very different and specific issues that may arise. With the help of the ADA, we have comprised a list of 5 concerns that a mature mouth might encounter.
1.) Gum disease. We know you’ve heard this one before, but the older you get the greater risk you are at. Brushing and flossing (the right way like we outlined in our 8 Common Brushing Mistakes article) combined with regular dental visits and periodontal exams is the winning combo to keep you healthy. Gingivitis is bad enough, but it is the reversible stage of gum disease. If your gum disease reaches periodontitis, it is irreversible.
2.) Missing teeth. Did you know that the average adult between the ages of 20-60 has three or more decayed or missing teeth? You may not think this is a big deal, but missing teeth can affect the way you eat and speak. Additionally, the missing tooth leaves an open space in your mouth that may cause your other teeth to move around or shift, and the vacancy in your mouth can also cause bone loss in that area where the tooth is missing. There are a handful of different solutions to solve this problem. Three of the most common are bridges, dentures, and implants. Call or visit us to discuss your options and together we can decide which option is best for you.
3.) Sensitivity. If you are experiencing discomfort when consuming hot and/or cold foods and beverages, then you may have sensitive teeth. This hyper-sensitivity could be caused by a number of things including tooth decay, fractured teeth, worn fillings, gum disease, worn tooth enamel, and/or an exposed tooth root. The good news is that sensitive teeth can be treated. Treatment may be as simple as desensitizing toothpaste, or maybe a more intense treatment is necessary for more extreme cases – treatment oftentimes depends on the cause of the sensitivity.
4.) Dry mouth. Dry mouth can be experienced by anyone, but if your mouth is constantly dry, then it may be time to seek treatment with us. Many things can cause dry mouth – medications, certain health conditions, and alcohol are a few of the more common causes. If you have constant dry mouth, it is important to get it checked because the reduced flow of saliva creates an environment where bacteria can thrive and decay becomes a real problem. Dry mouth itself is not a serious health problem, but making sure you take extra special care of your oral hygiene when/if you experience dry mouth is extremely important to maintaining a healthy mouth.
5.) Oropharyngeal Cancer. This can affect any area of the mouth – lips, gums, cheek lining, tongue, jaw, hard or soft palate, and throat. It can start as an unsuspecting white spot or inflamed area, so make sure to take it seriously if you notice something like this in your mouth. We regularly screen for oral cancers at your check ups because, as with all cancers, early detection is key to rapid recovery, prolonged health, and easier treatment options. Symptoms and warning signs of oral cancer may be, but are not necessarily limited to:
- Sores that bleed easily or do not heal
- A thick/hard spot or a lump
- A roughened or crusted area
- Numbness, pain, or tenderness
- A change in the way your teeth fit together when you bite down
- Difficulty chewing, speaking, and/or moving your tongue and jaw
We hope this information is helpful. Don’t neglect your oral health. It is extremely important to stay on top of these concerns so they do not progress as you age and become more difficult to deal with and correct. We are here to help! If you have any questions or concerns call us just to talk, or schedule an appointment.
