Some reasons your teeth are breaking and falling out are from age related changes, bruxism, "teeth grinding", trauma, gum disease or even poor oral hygiene.
Tooth decay, gum disease and plaque and tartar buildup are also causes of teeth breaking and falling out.
Tooth decay which is left untreated can weaken your teeth and make them more prone to breaking and falling out and gum disease which is a condition that damages your gums and bones that support your teeth, lead to loose teeth and potential tooth loss.
And plaque and tartar buildup can lead to gum disease and tooth decay.
A buildup of plaque is sticky film on the teeth and tartar is hardened plaque.
When a broken tooth does not hurt it's often because the nerve has died due to the impact of the fracture of the tooth.
The tooth my have already also been dead and is a reason the broken tooth doesn't hurt.
Also if the broken tooth hasn't reached the pulp, which is the nerve that contains the part of the tooth it won't cause pain even when broken.
To deaden a nerve in your tooth and stop nerve tooth pain you can use some clove oil applied to the affected tooth and gums and or use a cold compress or saltwater rinse.
You can also deaden the nerve in your tooth and stop tooth pain by using some Red Cross toothache medication which works wonders and very quickly.
When a tooth is black inside it is because of a condition called pulp necrosis which is the death of your tooth's internal tissues.
The pulp necrosis or death of your tooth's internal tissues can occur due to severe tooth decay, infection or trauma which can lead to the release of the dark pigments which stain your tooth black.
Having your tooth turn black inside is not normal and you should see a dentist.
The pulp that leads to pulp necrosis is located within your tooth and contains blood vessels and nerves.
And when the pulp in the teeth die and leads to necrosis it releases pigments which stain your dentin which is the layer below your tooth enamel and often colors the tooth a dark or blackish color.
Causes of pulp necrosis include severe tooth decay, trauma and infection...
Bacteria can enter the pulp through cracks or cavities in the teeth and cause an infection called pulpitis and can eventually lead to the pulp necrosis forming.
A blow or injury to your tooth or teeth can also damage the pulp and lead the pulps death and pulp necrosis and black teeth.
And if you have cavities which are left untreated, the cavities can also penetrate deep into your tooth and reach the pulp and cause infection and death of the pulp.
Other potential causes of pulp necrosis are tartar buildup, medications such as tetracycline antibiotics and old dental fillings.
If you have a black tooth you should see a dentist promptly for diagnoses and treatment and if the pulp is dead you may need a root canal to remove any dead tissue and prevent further damage.
And you may also need fillings, crowns or even a tooth extraction ins some cases.
