It seems like URL_Rewrite is not enabled or not working.
First thing you should do to check is placing ‘index.php’ in the URL like this  index.php/dental-chairs.html. If it works like this it means you just need to focus on rewrite.
After this, please check the database table ‘core_config_data’ and search for the path ‘web/seo/use_rewrites’, it’s value should be 1.
Now you need to check the following things:

• Server has rewrite mod working or not.
• .htaccess (if you are using apache) has the following:
  
  

<IfModule mod_rewrite.c>
    Options +FollowSymLinks
    RewriteEngine on
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    RewriteCond %{REQUEST_METHOD} ^TRAC[EK]
    RewriteRule .* - [L,R=405]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-l
    RewriteRule .* index.php [L]
</IfModule>
