Symptoms:
It starts with receding gums, uncovering the neck of the tooth, and a gap becomes noticeable between the gum and the tooth. This is not attributed to cavities or aggressive brushing, as we are often told, but rather to a poor distribution of forces and is a condition or pathology called abfraction.
Abfraction is a cervical lesion where there is greater exposure of the tooth's neck, leading to increased sensitivity. With this lesion, it begins to accumulate more dental plaque, causing even greater sensitivity, and there may also be a change in color.
Why does the lesion cause so much pain?
Because in the center of the tooth, we have dental pulp, which is a soft tissue that contains the nerve responsible for transmitting pain and sensitivity. Around it, we have very small veins and arteries that supply nutrition to the tooth. The second tissue is dentin, which is full of channels (tubules) containing nerve endings that transmit heat and cold stimuli to the pulp. This is why dental sensitivity occurs when it is exposed.
What can be the origin?
Poor tooth positioning, which can be corrected with orthodontics.
Bruxism: because teeth are being clenched or grinding heavily at night, which generates excessive forces on the teeth until they can no longer withstand the pressure, leading to fractures in the enamel at the neck of the teeth.
Treatment:
We apply laser to melt the crystals and seal these tubules, preventing sensations of cold or heat from passing through and blocking them. We counteract the open tubules that are transmitting sensations to the pulp, and then we use a special resin to fill the space to control and manage sensitivity.
If you have any sensitivity issues, do not hesitate to schedule an assessment appointment to find a solution for your problem. At Dr.|A® Dentistry, we have a team of specialists who will analyze each case and provide the best solution to restore your smile.
