Losing teeth is minor damage but a significant shock for an adult. People aged between 35 to 44 lost at least one tooth, and by the age of 74, most people lose almost all their teeth. There are various reasons for tooth loss. It can be due to tooth decay, periodontal disease, gum disease, or wear and tear. For whichever reason you lose a tooth, you should replace the lost tooth with a new one. When a person loses the teeth, adjacent teeth start to shift its place in the mouth. It affects the look of your smile. The jaw bone of that region begins to recede as it has no tooth. The shifting of teeth makes regular oral care routine like brushing and flossing challenging. You might start facing problems in chewing your food also, especially in older adults, it can cause a lack of nutrition.
There are many techniques for replacing a lost tooth. The most popular choices for replacement of a tooth are dental bridges and dental implants. Dental implants are an artificial tooth that fits with the help of a small titanium screw on your jaw bone. Gradually the tissue around the artificial tooth starts to grow and holds the implant in the place. A dentist places the dental crown on the implants to give it a natural look. You can use implants for either one or many missing teeth. Though dental implants are a suitable replacement for lost teeth, dental implants can get uncomfortable with age, and the healing process also takes time. The procedure of screwing the teeth to the jaw bone can sometimes be a failure. As your body ages, it might not adapt to the shape of your mouth. Therefore, science has come up with a new technique that will let a patient grow new teeth inside the mouth itself.
The stem cells from the dental pulp are an excellent way to replace damaged teeth. Stem cells from the growing tooth roots and periodontal ligaments play a different role in tooth development. Dentists can easily extract dental stem cells, which makes them an excellent way to regenerate pulp tissue, periodontal ligament, or for growing partial or complete teeth.
According to a study, a patient can regrow their tooth in the empty socket with the adjacent gum tissues. It is possible with the help of a patient’s stem cells in nine weeks. This procedure of growing new teeth has many advantages over the other techniques. Using this technique, one can regrow a severely injured or damaged jaw also. You do not need to create an environment outside the body to grow the teeth, let it mature, and then implant it. Practitioners can guide stem cells to a socket where the tooth can grow and blend with the surrounding tissue.
A group of researchers experimented on 22 rats. Firstly, to mimic dental caries, they punctured into the molars of each of the rats. Then, scientists put the stem cells of an adult into the center of the drilled tooth of the rats. Then, they stimulated the stem cells using minimal energy laser with less intensity, and then they sealed it using a temporary cap for the subsequent twelve weeks. After that, the scientists conducted x-rays and observed that the dentin present under the enamel has grown due to this therapy. This study is a significant breakthrough for the potential application of stem cells to develop teeth in humans.
Using Dental stem cells
The first step in extracting stem cells consists of separating various groups of the cell with stem cell properties from multiple parts of the tooth. These cells comprise cells from the tooth ligament, growing roots, and dental tissues. They have features similar to the stem cells from the embryonic connective tissue. The dental stem cells have the power of rebuilding damaged dentin, enamel, bones, nerves, and dental pulp.
The new dentistry technique allows the regrowth of lost teeth biologically with the help of dental stem cells. It needs the crucial parts to grow a functional tooth, which includes nerve, blood vessels, periodontal ligament, and roots. Although the crown is necessary, it is less critical as it can match with a synthetic top of the right size, color, and shape. Therefore, the only difficulty is to form the biological root of tooth replacement.
Keeping Stem cells healthy for tooth restoration
The use of healthy stem cells increases the chances of tooth regeneration. Therefore, it is essential to have healthy dental pulp that contains stem cells. A pulp is healthy when the tooth has an unimpaired blood supply, doesn’t have infection, caries, or other pathogenesis. Stem cells are available throughout the veins and nerve present inside the pulp. It is advisable to retrieve stem cells when you are young, fit, and healthy as at this time, stem cells are highly active in terms of production and growth of new cells. Dentists can retrieve stem cells from a healthy permanent tooth of a middle-aged person. With growing age, these stem cells reduce production and rapid growth. Therefore, the sooner the stem cells recover, the higher are the chances of growth.
Once the stem cells restore, you can preserve them for future use with the help of cell preservation technology. This technology existed for a long time for the banking of umbilical cord stem cells. Now, for storing dental stem cells, there is another bank of stem cells. The dental stem cell restoration happens in three steps- a collection of the tooth, isolating stem cells, and storing tooth cells in liquid nitrogen below 150-degree celsius.
There is a massive development in the science of dentistry, starting with first prevention, then conservation, and now regeneration. Stem cell therapy enables dentists to look beyond implants and restorations. Although it has certain limitations like patient reception, ethical concerns, and economic practicability. These stem cells are useful in treating some chronic illnesses also. Science is still facing many challenges associated with the process of isolating stem cells. Still, to make this therapy a feasible choice in dentistry, there needs to be more research and awareness in this field. Consult your dentist to know the best procedure for your tooth replacement. They will suggest the right treatment based on the positions of the lost teeth. Before booking an appointment with a dentist, google “good dentist near me” and schedule a consultation with the one with good reviews.
