Root canals are the recommended process by which to remove diseased or necrotic tissue from the nerve canal of a tooth. Ideally, it is in your best interests to save your teeth with root canals rather than to have them removed and replaced with bridgework – which would ultimately end up being more expensive.
The most common reasons for a diseased nerve are deep, untreated cavities or traumatic injuries or damage to teeth. Symptoms can include high sensitivity to hot or cold, pain when biting, or even facial swelling.
After root canals, porcelain crowns are placed over the tooth to strengthen its structure and improve appearance. In some cases, root canals may cause temporary minor swelling and discomfort, easily controlled with over-the-counter medications.
Thanks to the very effective anaesthetic solutions now available, root canals are no longer the traumatic procedures they were once believed to be. In fact, in 95% of cases they are entirely uneventful and recovery is quick and easy.
