What a beautiful area Fife is .This is Tentsmuir near St Andrews in January .A cold wind blowing which is nice unless you happen to have a bit of sensitivity.Sensitivity due to gum recession is very common and can affect most age groups.The symptoms are pain with cold or acidic foods drinks and cold air .Typically the pain goes away once the stimulus is removed and does not leave a lasting pain.There are many types of sensitive tooth pastes around eg sensodyne,colgate sensitive pro relief.Also there are some treatments available from your dentist which can be very effective.Please ask your dentist or hygienist if this is bothering you.
