A tooth may also alter colour following an accident, fall, sports injury or sudden impact. The initial tooth may look normal. However, the tooth may become of a yellow, grey, brown or black colour. The discoloured tooth after trauma may just appear to be a stain. But, the colour change can sometimes be indicative of an injury within the tooth.
The trauma can damage the blood vessels, nerve or soft tissue inside the tooth. Sometimes the tooth will heal without treatment while in other instances the nerve tissue will die or be damaged. Catching these early changes can prevent additional problems.
In this blog, we will discuss why teeth darken after trauma, how to recognize signs of nerve damage. Also, the available treatments, and whether a darkened tooth can still be saved.
Why Does a Tooth Darken After Trauma?
A hard blow can cause damage to the inside of the tooth without the outside being broken or chipped.
The blow might damage the blood supply, nerve and soft tissues leaving the tooth gradually yellow or grey/brown/black. Although, discolouration may be immediate or delayed.
Bleeding Inside the Tooth
Trauma can break tiny blood vessels inside the tooth. When this happens, blood can enter the surrounding dentin. As the blood cells break down, their pigments may remain within the tooth and gradually change its colour.
This can make the tooth look darker over time. The change may appear within days or become noticeable several weeks later. Although the colour may look concerning, bleeding alone does not always mean the tooth has lost its vitality.
Damage to the Tooth Nerve
The force of a heavy blow can damage the nerve and blood supply in the tooth. The pulp tissue can sometimes recover if there has been a minor injury. But more serious trauma may interfere with the pulp tissue’s blood supply.
If the damage persists, the tooth will begin to lose its normal vitality and darken over time. A dark tooth after trauma may therefore, require professional assessment even when asymptomatic or with no hypersensitivity.
Pulp Inflammation or Death
The pulp may become inflamed after a traumatic injury. In mild cases, it can recover with time. However, severe damage may prevent the pulp from healing properly. If the pulp eventually dies, the tooth can become grey, brown, or dark.
It may also stop responding normally to hot or cold sensations. Still, tooth colour alone cannot confirm pulp death. A dentist may use clinical tests, X-rays to assess its condition and recommend root canal treatment in Patna.
Infection Inside the Tooth
A damaged or dead pulp can create an environment where bacteria grow inside the tooth. The infection may then travel toward the root and surrounding tissues. This can cause further darkening along with symptoms such as pain while biting, swelling, tenderness, or a small bump on the gum.
But some dental infections don’t have many symptoms in the early stages. For this reason, any tooth discoloration after trauma should be investigated and not simply treated as a cosmetic stain.
Cracks or Fractures
A fall, accident or sports injury may result in a fractured or cracked tooth. If the crack is sufficiently deep, the bacteria from the mouth can reach the pulp and cause pulp disease. This may cause the tooth to change colour. A fractured or cracked tooth can also cause the tooth to be sensitive to biting or hot/cold foods.
Symptoms will vary depending on where the fracture is and how deep it is. A dental evaluation can detect cracks in teeth that aren’t visible at home.
Not one but several things may result in a darkened tooth so looking at how it looks can’t tell you the reason. Front tooth discoloration after trauma must be looked at by a dentist, especially if the colour is still changing or there are other signs.
Recognizing the Signs of Dead Tooth Nerve
A lost or injured nerve in the tooth is not always painful. Occasionally, the tooth simply no longer responds after a trauma, and this can happen without much of an indication to the patient. Changes in colour or sensitivity in the tooth, and changes in the gum can provide helpful clues.
Common signs may include:
- Persistent tooth discoloration: The tooth may gradually turn grey, brown, or black after trauma. However, colour alone cannot confirm nerve death.
- Loss of temperature sensitivity: A damaged nerve may stop responding normally to hot or cold sensations.
- Pain or tenderness: Pain while biting, chewing, or touching the tooth may indicate inflammation or infection.
- Swelling around the tooth: Swollen gums or a small pimple near the tooth may indicate infection around the root.
If these signs appear after an injury, a dental check up or examination can determine whether the tooth needs monitoring or treatment.
Treatment for Dark Tooth After Trauma in Patna
Treatment depends on why the tooth became dark and whether the pulp remains healthy. A dentist may first examine the tooth, check its response to temperature or other tests, and take an X-ray if needed. For patients seeking trauma treatment in Patna, the appropriate option depends on the condition of the tooth and the extent of internal damage.
Common treatment options include:
- Monitoring: If the tooth remains healthy and shows no signs of infection, the dentist may recommend regular check-ups instead of immediate treatment.
- Root Canal Treatment: If the pulp dies or becomes infected after trauma, root canal treatment can remove the damaged tissue, clean the tooth from inside, and seal it. In Patna, RCT will cost around ₹4,000 – ₹6,500, depending on the clinic and complexity.
- Internal Bleaching: If the tooth remains dark after the infection or pulp problem has been treated, internal bleaching may help lighten the colour from inside. The approximate cost may range from ₹2,000 – ₹5,000.
- Dental Crown: A severely weakened or brittle tooth may need a crown for added protection. Depending on the material, such as ceramic, zirconia, or metal-fused options, the approximate cost can range from ₹3,000 – ₹8,005.
The aim is not to just whiten a dark tooth. First, the real problem must first be identified and treated. Once the tooth is stable, then a safe cosmetic treatment can be explored to improve its appearance.
Can a Dark Tooth After Trauma be Saved?
Yes, many of our dark tooth after trauma can be saved, but it depends on how much damage has occurred.
First, the dentist will assess your tooth’s pulp and root, as well as the bone around your tooth and the overall damage. Root canal may allow us to preserve your natural tooth.
As long as the tooth’s structure is sound, the treatment can restore its function and appearance. When the tooth is healthy enough, bleaching inside the tooth or placing a restoration can give the tooth an improved colour.
Severe cracked or severely damaged teeth may need extensive treatments, the earlier on that you visit a dentist, the more the dentist can try to save the tooth.
