Growing New Teeth With Stem Cells - Odontis

cosmetic-teeth-odontis

In 2004 scientists at King's College London set up a company called Odontis. They have been working on developing human teeth from stem cells. This biological replacement tooth has been trademarked as BioTooth.

The idea is to take adult stem cells, treat them in a cell culture so they would be programmed to develop into teeth and then transplanted into the patients jaw where the gap is. Then a replacement tooth grows just as happens when humans grow their original adult teeth. It is thought it would then take two to three months for the tooth to fully develop. The cost should not be more than existing treatments making it an attractive alternative to other technologies such as implants and dentures.

By 2007 Dr. Paul Sharpe and his team had learned to control the type of tooth formed and control the basic shapes, i.e. molar, incisor. Tooth development involves a network of thousands of genes. It's not necessary to understand what all the genes are doing to get the ball rolling, Sharpe says. Rather, by watching when a few key genes are turned on and off, the researchers have learned which are most important in the control of size and shape. Some genes only work in the upper jaw, others only where molars grow. In one experiment, Sharpe's team took early tooth buds from growing embryos and switched on a gene known to be active in growing molars. They implanted the buds in the front of the jaws of mice, where incisors would normally grow. The rodents emerged with molars in front and back.

The teeth are grown in mice kidney capsules because they provide a convenient site for prolonged growth due to the bountiful blood supply to the developing tooth. Dr. Sharpe’s aim was never to grow teeth in kidneys. This is just his experimental test system. In the future its likely that the teeth will be grown in some sort of artificial bio-reactor which itself is still in development.

The tooth bud is then implanted in the jaw and the gum stitched or sealed with a clinical "glue". They have not started human clinical trials yet, however they expect the procedure to be less invasive than a tooth extraction and the requirements for post-procedure care would be similar. After implantation it takes the tooth about 3 weeks to set in the jaw of a mouse. As long as the tooth is not under heavy load, it sets well.

The technology to grow replacement teeth could mean the end of dentures. Living teeth would be much better than dentures because they can respond to a persons bite. They move and in doing so they maintain the health of the surrounding gums and teeth. Dr. Sharpe has patented the technique and hopes to begin human trials in a few years once they perfect their techniques.

Predicting a release date to market is difficult as its still in development but according to their website they are expecting it to be available in "several years".

It looks like the whole tooth regeneration is a too much long-term goal but what about partial tooth regeneration? I have a first molar that is treated with root canal therapy and have a porcelaine crown on it cause it lacks a lot of dentin due to decay. Now I wonder if at least pulp-dentin regeneration is a more reasonable short-term goal in dentistry. At least a a live tooth with an artificial crown , yet not a new tooth from scratch is pretty functional. In San Antonio some specialists have already revitalised a tooth of a 12 y.o. boy and now they say they will try the same treament in adults. I would like to participate in the trials, too bad I live in Spain.

How can I be apart of this research I am willing to let you use my mouth toprove it works I only have 7 teeth in my mouth and have been told that faose teeth would not fit my mouth as my gums are to small to hold a false plate I am 58 years and have always smiled all the time but I no longer smile as I dont have the teeth to smile with please allow me to help you as well as help myself.

Looks like they're mainly working with Recaldent which remineralises teeth on application.
Dental decay, or caries, start when bacteria in plaque produces an organic acid which dissolves the tooth enamel, breaking down the calcium and phosphate in tooth enamel.
Recaldent™ works by delivering calcium and phosphate ions into the tooth, repairing and strengthening areas of enamel previously damaged by the action of bacteria.

I hope this growing new teeth happens soon. When I was 12 I caught a pop fly baseball that I lost in the sun and it knocked all my teeth loose. After that my teeth started to loose there enamel and I have lost teeth to decay and breaks, have tons of fillings. At the age of 40 would love a new smile of nice white teeth again.

Im pretty sure the Bio tooth will be available soon , i look forward for enamel regeneration tecnology , i need to get rid of my veeners-crowns that i did for comestic they bother me soo much :laugh:

lets get together and make it happen , something huge is coming on the conference in april

Instead of a mouse kidney capsule if the stem cells could be grown in a lab it would be much faster & viable. Also could cells from the nerve (pulp chamber) of the extracted tooth be useful in any way to hasten the process

what is new guys about teeth regrowing? when will start clinical trial?

I asked both of them, I was intereseted in teeth regenertion, whole tooth, dentin, pulp, enamel, what they did on mice 2007 and they said that tooth regeneration it could be possible in 10-20 years. I Asked PAUL SHARPE are there going to be any trial regarding regeneration of teeth and he answered that thay are not planing any trial. I am interested in this like you I dont have reason to lie. And I would love to hear that I am wrong. Greetings

Lets not get confused between Odontis and their original Biotooth with the conference coming up next month (April 11) with the leading tooth stem cell scientists in New York. I notice this thread started from the Odontis article but the comments since drifted toward discussing Dr Mao and his technology which may be misleading readers of the Odontis article. Maybe its time to start a new thread???

Could I suggest commenting in the future on Dr Mao and the New York conference here www.upgradeyourbody.com/articles/dental/...-getting-closer.html

Thanks

@ djssla
you did not write what was Dr. Sharpe's answer?
He wrote me that Odontis is no longer active.The company fail to secure grant due to delay of their research. What answer he gave you?

no hoppe tom move on your life.. I am sorry. I asked Paul Sharpe, Takashi Tsuji, they are the leader ine teeth regeneration and if they said nothing, then others can t do also nothing greetings

you are sure what after 20 years we will can regrow teeth in application? or are we just expectining? why can't faster regrow? minces and pigs regrowing teeth is in practice. why human biotooth is tabu?

ear Sir/Madam

I'm sorry for late reply.
Thank you for your additional question.
At present, this is still in the fundamental research phase,so we have not
trial on a human yet.
we think that it is expected that over 10-20 years are still needed for a
practical application.

yours faithfully.

Takashi Tsuji, PhD
That was answer
