hello
thanks for sharing your query ,

as soon as trauma strike teeth the blood vessels and nerves gets within tooth gets injured resulting in pain and bleeding from the tooth...slowly slowly blood supply to the tooth stops resulting in dead pulp/necrosed pulp ,now this necrotic pulp causes dark discoloration of the tooth..

if the tooth is intact its advised not to extract it but only removal of the necrotic pulp and go for a prosthetic crown over it...

take care ...

Hello,
Thanks for posting your query,
Tooth darkening or discoloration after a trauma is similar to a bruise on the skin. It is the result of internal bleeding in the pulp chamber (the cavity in the central portion of the tooth that contains blood vessels and nerves). In a mild tooth trauma, tooth discoloration disappears automatically in several weeks, which means the nerve is still intact. If the discoloration remains or gets darker over time (usually several months), this indicates the death of the dental pulp chamber.
I hope this information has been both informative and helpful

Hi,

Thanks for asking the query,

Trauma to the tooth may cause necrosis, discolouratiion . If the blood vessels deep inside the tooth breaks, the blood may be absorbed into the tiny tubules that travel from inside the tubules to the outer enamel layer, as the enamel is translucent so you can see the discolouration.

I suggest you to visit to the Dentist and get the checkup done .
If there no pain symptoms ignore the problem as this tooth will be replaced in 2-3 years.
If the tooth is associated with pain and swelling , get an x-ray done depending on which the treatment will be decided.

Hope this helps out.

Regards....

hello there ,

Physical trauma or impact injury to the teeth leads to necrosis or death of the dental nerve tissue leading to discoloration of the teeth.

the dental pulp or the nerve tissue in the tooth gets necrosed forming a black thread like structure which gives bluish or black hue to the teeth.

such devital teeth needs to be treated by PULPECTOMY procedure which removes the dead pulp , disinfects the canals and fills it with permanent canal seling material.

i hope this information helps you ,

take care.

Dear friend.

Thanks for sharing your concern.

The cause for discoloration of teeth are due to lysis of red blood cell.

upon destruction the red blood cell releases a pigment which bring about the discoloration of teeth.

Also, it indicates that the teeth has become non vital after suffering from trauma.

Therefore it is advised to revisit your pedodontist and discuss if the tooth can be retained as space maintainer or should be extracted.

Hope this helps you.

Thanks.

Take care.

hi...
thanks for the query...
front teeth of your daughter seems to be necrotic... in necrosis, the blood cells and blood vessels undergo degeneration and die... and the by products, enter the dentinal tubules of the tooth, hence darken them...
because teeth are primary, so not to worry much... but they are important too, so i think you should go for their root canal treatment and should get proper radiographic examination done...
please consult pedodontist also...
hope it will help you...
take care...

Hello,
I am Dr.Neha Gupta (dentist) and am glad to address to your query here.

The extent of discolouration of the tooth after trauma depends upon the severity of the shock or injury. Post trauma internal bleeding in the pulp chamber is mainly responsible for tooth discoloration.

Discolouration of tooth after trauma requires sometimes requires advanced medical treatment in order to preserve the traumatised tooth.

Hi,
Welcome to HCM forum,

Tooth discoloration after injury means that the pulp is affected due to trauma.

So consult a dentist for the radiograph of that tooth then on the basis of radiographical examination treatment of tooth has to be decided.

Wishing your daughter a cure soon

Hi,
The trauma to your childs teeth has resulted in the discoloration. The tooth is becoming non-vital. That is the pulp inside the tooth has become dead. The treatment for it is Root canal treatment. The tooth should remain until 7 years when the permanent teeth will erupt out.

Hi there,
Thank you for posting your query.

Good that you have taken your daughter to a pediatric dentist and have followed treatment regimen.If your child's tooth has turned dark, the best thing to do is to have your Pediatric dentist look at it. If there are other signs that the tooth is dead such as swelling or an infection that is shown on the x-ray, then your pediatric dentist will probably choose to perform a root canal treatment or removing the tooth. if clinical or radiographic symptom are not present then your dentist will leave primary teeth for their permanent successors.

It is important to understand that "in the primary dentition of a healthy child, color change alone does not indicate a need for pulp therapy or extraction of the tooth .

Basically, if your daughter's baby tooth has changed color, often the best treatment is no treatment. As long as an infection doesn't develop, simply waiting it out and seeing what happens could mean that your child doesn't have to go through unnecessary dental treatment. And that's a good thing, especially after they've already been through a traumatic tooth injury.

hope this helps you
regards

Dentist, Endodontics Dr. Manisha Rao's  Response
Hi, the discoloration of teeth is due to trauma. For your knowledge i must tell you that every tooth has pulp tissue inside it. Due to forceful trauma to teeth, there is bone damage around the root of the tooth. There is pus formation around the root. The pulp tissue gets necrosed or damaged completely. The infection travels from root to tooth and vice versa. The colour of the tooth appears brown or black due to this pulp death. Please get the teeth treated by a root canal treatment if they start giving pain. The front teeth fall off at the age of 6-7 years. If there are no symptoms, you can just ignore the discoloration. If there is pain, swelling or pus formation, the teeth will need treatment or extraction. Take care!
