Topical anesthetics act on the peripheral nerves and reduce the sensation of pain
at the site of application. In dentistry, they are used to control local pain
caused by needling, placement of orthodontic bands, the vomiting reflex, oral
mucositis, and rubber-dam clamp placement. Traditional topical anesthetics
contain lidocaine or benzocaine as active ingredients and are used in the form of
solutions, creams, gels, and sprays. Eutectic mixtures of local anesthesia cream,
a mixture of various topical anesthetics, has been reported to be more potent
than other anesthetics. Recently, new products with modified ingredients and
application methods have been introduced into the market. These products may be
used for mild pain during periodontal treatment, such as scaling. Dentists should
be aware that topical anesthetics, although rare, might induce allergic reactions
or side effects as a result of an overdose. Topical anesthetics are useful aids
during dental treatment, as they reduce dental phobia, especially in children, by
mitigating discomfort and pain.
