At-home treatments include desensitizing toothpastes or dentifrices, potassium salts, mouthwashes and chewing gums. A variety of toothpastes are marketed for dentin hypersensitivity, including compounds such as strontium chloride, strontium acetate, arginine, calcium carbonate, hydroxyapatite and calcium sodium phosphosilicate.
Recently, laser treatment has been proposed as a potential method of treating dentine hypersensitivity. Low-output lasers may be used to block the electric transmission of stimuli to pulpal nerves whereas high-output lasers are being considered as an alternate method of occluding the dentinal tubules. [ 58 ]
The glutaraldehyde in Gluma works by occluding (blocking) the microscopic tubules that compose dentin, thereby preventing the flow of fluid and decreasing sensitivity. [4] Gluteraldehyde induces coagulation of proteins in dentinal tubules, which reacts with the serum albumin in the dentinal fluid to cause its precipitation.
The pulp of the tooth remains normal and healthy in dentin hypersensitivity. [10]: 510 Many topical treatments for dentin hypersensitivity are available, including desensitizing toothpastes and protective varnishes that coat the exposed dentin surface. [16] Treatment of the root cause is critical, as topical measures are typically short lasting.
Silver diammine fluoride (SDF), also known as silver diamine fluoride in most of the dental literature (although this is a chemical misnomer), is a topical medication used to treat and prevent dental caries (tooth decay) and relieve dentinal hypersensitivity. [1]
If the attrition is severe, the enamel can be completely worn away leaving underlying dentin exposed, resulting in an increased risk of dental caries and dentin hypersensitivity. It is best to identify pathological attrition at an early stage to prevent unnecessary loss of tooth structure as enamel does not regenerate.
[48] [49] Although it varies from person to person, sensitivity after whitening treatment can last up to 4–39 days. [ 50 ] [ 51 ] Potassium nitrate and sodium fluoride in toothpastes are used to ease discomfort following bleaching, however, there is no evidence to suggest that this is a permanent method to eradicate the issue of hypersensitivity.
In comparison to alternative treatments for dentine hypersensitivity relief, nano-hydroxyapatite containing treatment has been shown to perform better clinically. Nano-hydroxyapatite was proven to be better than other treatments at reducing sensitivity against evaporative stimuli, such as an air blast, and tactile stimuli, such as tapping the ...
