They are not as common as in winter, but respiratory infections such as colds and flu also appear in summer. These processes can be associated with toothache, in addition to benefiting the appearance of oral pathologies that can be avoided with simple prevention measures. The reason we can suffer toothache is that some influenza processes are accompanied by inflammation of the paranasal and maxillary sinuses (sinusitis), the latter located just above the upper molars. Inflammation of structures near the nerves causes their stimulation when compressed.
On the other hand, the usual nasal congestion causes it to breathe through the mouth, which increases dryness, a situation that increases the risk of irritation and the appearance of caries. The College of Dentists of Santa Cruz de Tenerife recommends increasing water intake to avoid this dryness and, in case of drinking infusions and acid juices, we must not forget dental hygiene, to neutralize the possible harmful effects on tooth enamel.
In addition, if the flu process is accompanied by vomiting, it is advisable to rinse your mouth with water (or better with milk) and not brush your teeth immediately. If the respiratory infection is of bacterial origin it is important to change the toothbrush when overcoming the infectious process, since bacteria can survive in this essential instrument of dental hygiene, which will cause healing to take longer.
