Indead tooth is a condition where the pulp of the tooth, i.e. the nerves and blood vessels, has died. This often happens as a result of caries, trauma or prolonged stress. The tooth may be asymptomatic, but risks causing infection if not treated in time.
"A dead tooth can go unnoticed, but it is important to have it examined in time. With the right treatment, we can both preserve the function of the tooth and prevent more serious infections."
- Erik, dentist at Dentme
What is a dead tooth?
A dead tooth (necrotic tooth) has lost its blood supply. When the pulp inside the tooth dies, the tissue stops functioning, creating an environment where bacteria can easily enter and cause infection.
Causes of tooth death
Common causes are:
- Depthcaries - bacteria penetrate the pulp
- Trauma - for example, a blow to the tooth
- Tooth grinding - constant strain that damages the tissue
- Cracks in the tooth - giving bacteria a way in
- Leaky or old fillings - letting in bacteria
Symptoms of a dead tooth
A dead tooth can be completely asymptomatic, but often it is noticeable through:
- Dull or persistent toothache
- Soreness when chewing
- Discoloration (grey, blue or yellow-brown)
What a dead tooth looks like
The tooth may look discolored but appear normal on the surface. An X-ray will reveal if the pulp is dead or if there is an infection.
Treatment of a dead tooth
Depending on the extent of the damage, different options are available:
- Root canal treatment - the pulp is removed and the root canal is filled
- Crown - protects a root canal treated tooth from fractures
- Red tip surgery - for infections that do not heal with standard treatment
- Extraction and dental implants - if the tooth cannot be saved
Bad taste in the mouth - what causes it?
Having a persistent bad taste in your mouth is common, but should be taken seriously if it does not go away. Often it is a problem in the mouth, but sometimes other diseases can be the cause.
Common causes of bad taste
- Poor oral hygiene - bacterial deposits on teeth and tongue
-Gingivitis (gingivitis or periodontitis) - common and often hidden
- Dry mouth - saliva deficiency increases bacterial growth
-Fungus in the mouth (oral candidiasis) - often gives bitter or metallic taste
- Wisdom teeth - infection around these can cause bad taste
- Reflux or sinusitis - can affect the taste indirectly
How to get rid of bad taste in your mouth
- Brush teeth and tongue twice daily with fluoride toothpaste
- Use dental floss and tongue depressors
- Drink water regularly
- Avoid smoking and sugar
- Visit the dentist for examination and cleaning
- Use saliva stimulants for dry mouth
