Sinus infection or sinusitis is primarily an inflammation of your nasal passage lining that can develop into acute sinus infections. The pressure that the bacterial mucus builds up may assert itself on the dental nerve endings and can cause a severe toothache.

Here are 5 tooth pain relief techniques that can alleviate the discomfort in your mouth due to sinus infection :

• Fluid intake and the inhalation of steam:  This helps to stay hydrated as well as hydrates the mucous membranes and decreases the level of mucus that has built up inside the nasal cavity. Drinking coconut water, which is rich in electrolytes and contains magnesium, helps in hydrating your body quicker.
• Spicy food :  Spicy food such as chilies and pepper have mucus thinning properties and thus give you instant tooth pain relief. Consultation with a doctor is imperative because not every spicy food is effective in treating sinusitis and relieving toothache .
• Sleeping over the sinus pain :  This may sound like an excuse, but only a few people are aware of the fact that the resistance system of one’s body is more active when the body is at rest. While a person is asleep, there is an ample production of white blood cells which enhances the immunity of the body. Humming has also been reported to be effective in lowering tooth pain because air flow increases during humming and clears the mucus buildup.
• Use an expectorant:  Expectorants are known to melt the mucus buildup. The decongestants dry out the passage and thus relieve the pressure to provide tooth pain relief.
• Positioning your head for the best drainage:   While one is suffering from sinus pain, it is advisable to rest by keeping the head propped up or in a tilted position. This is a better way to drain the nasal passage, as lying flat on one’s back can lead to continued pressure on the nasal cavity.
