is then spit out. Disclosing gels will show the presence of the plaque, but will often not show the level of maturity of the plaque. Disclosing tablets are often prescribed or given to patients with orthodontic appliances for use before and after tooth brushing to ensure optimal cleaning. These are also helpful educational tools for young children or patients who are struggling to remove dental plaque in certain areas. Disclosing gels and tablets are useful for individuals of all ages in ensuring efficient dental plaque removal. Visual or tactile detection Dental biofilm begins to form on the tooth only minutes after brushing. It can be difficult to see dental plaque on the hard tissue surfaces, however it can be felt as a rough surface. It is often felt as a thick, fur-like deposit that may present as a yellow, tan or brown stain. These deposits are commonly found on teeth or dental appliances such as orthodontic brackets. The most common way dental plaque is assessed is through dental assessment in the dental clinic where dental instruments are able to scrape up some plaque. The most common areas where patients find plaque are between the teeth and along the cervical margins. Plaque in dogs and cats Dental plaque is also extremely common in domestic animals such as dogs and cats. However, the bacteria associated with canine and feline plaque appear to be different from those of humans. If untreated it can lead to more severe gum disease such as periodontitis; hence veterinarians often recommend oral healthcare products for affected pets.
