Root canal treatment is a procedure to restore your original tooth for functional and esthetic purpose. One can start to eat post a root canal therapy within one to one and a half hours time as soon as the effect of anesthesia wears off. This treatment is often or always followed by placement of a prosthetic crown or bridge when multiple teeth are involved. The functional activities involve eating on the side of the treated tooth, speech and brushing. Talking about the chewing factor, the crown placed on the tooth is such that it is designed anatomically to that of the natural tooth or teeth treated. The occlusion or bite forces are recorded during the first impression made for the crown. The fabrication involves shaping or designing the treated tooth to accept the crown in such a manner that it resembles and adapts functionally with the surrounding present healthy teeth. All this fabrication helps an individual to chew regularly the non-sticky food items. So to prolong the functional activity of the tooth one should avoid hard nuts as the pressure created would directly be transferred from the crown to your already compromised root canal treated tooth. The impact of the masticatory forces directed towards the tooth is not well tolerated compared to a natural healthy tooth or teeth.
Hence apart from sticky and hard food items patients can easily consume regular food items by root canal treated tooth. A root canal treated tooth alone cannot withstand one’s masticatory forces. It needs adjacent teeth to function along with it.
